21 Famous People Who Surprisingly Attended Kylie's 21st Birthday Bash

As any other member of the Kardashian-Jenner family has proved in the past, celebrating milestones is something the crew takes very seriously. And the 'Keeping Up With The Kardashians' stars definitely know how to throw a party when needed. From Kylie and Khloe's all-pink baby shower to the adorable North West and Penelope Disick's unicorn birthday party in Calabasas we're pretty sure you got a taste of how much epicness a Kardashian party can reserve.

And Kylie decided to carry on the family tradition and celebrate her 21st birthday in great style surrounded by her family and (famous) friends at a lavish bash. We'll quickly recap a few of the most noteworthy things that were present at Kylie Jenner's birthday party, just to give you an idea of the unbelievable party vibes Kylie delivered. After an intimate dinner at Craig's, an exclusive blowout bash at Beverly Hills hot spot Delilah followed.

That's where the party really took off: ball pits, murals, Kylie-themed cookies and the security guards wearing the Forbes cover on which Kylie has been called “the youngest billionaire”. Uh, and the inevitable photo booth (would it even be a Kardashian party without one??). Wow, Kylie, that's a night you definitely won't forget!

But you know, an epic party must include epic guests to be really considered one. Keep reading to find out which A-list celebrities attended Kylie's 21st birthday party!

20 Her Beau: Travis Scott

Of course, Travis Scott couldn't miss the birthday girl's party for the world. The young couple enjoyed Kylie's 21st birthday party in perfect Kardashian style: enjoying lots of PDA moments, good food and even rolling together in a huge pink ball pit (no less!). The two seemed inseparable throughout the whole party and Kylie even jokingly used a “single” yellow cup.

Also, slow-claps for Travis for absolutely nailing Kylie's birthday present. Remember the $1,4 million Ferrari he gave her after Stormi's delivery? Well, it definitely seems the “Astroworld” singer and producer likes gifting her girlfriend cars.

The rapper, indeed, went ahead and threw down for a vintage Rolls Royce, which Kylie found parked in her driveway on the morning of her birthday.

As a cherry on top, he also decked out her home in roses!

19 Integral Part Of The Model Crew: Bella Hadid

As one of Kendall and Kylie Jenner's best friends, it's no surprise that Bella Hadid helped ring in Kylie's big day. Like many other celebrities present at the party, the supermodel enjoyed documenting the night on her social media story, posting a fun video of Kendall posing for the camera in a mirror.

It wasn't hard to notice that the youngest Hadid sister showed up to the party with The Weeknd - an old flame she recently got back together with and who also posted on social media from the party. Just last month, Hadid and Tesfaye were spotted on a date in Tokyo where they attended Tokyo's famous robot restaurant. During that occasion, The Weeknd shared a clip on social media which showed Hadid sitting next to him, laughing and visibly enjoying the show.

18 Bella's On-Again-Off-Again Man: The Weeknd

After months of speculation regarding the status of their relationship, it appears that Bella Hadid and The Weeknd are now officially back together. After being spotted together on various occasions and even engaging on social media like a real couple (they started following each other again for example!), the two seem to be going stronger than ever. So it's no surprise they attended Kylie's 21st birthday party together.

On his social media story, The Weeknd shared a cute video to document the party that shows Hadid and Kendall dancing together, while Hadid smiles.

The party's photo booth (they posed together) and Kim Kardashian's Snapchat Stories (she panned the camera over the crowd to see The Weeknd dancing nearby Hadid!) only further confirmed that the two can't stay away from one another.

17 The OG Model: Cara Delevingne

A close friend of supermodels Bella and Kendall - as well as of the birthday girl herself - Cara Delevingne couldn't miss Kylie's 21st epic birthday party. The three supermodels reportedly spent the “majority of the night” together, as a source told E! and had a lot of fun taking pictures and dancing.

The actress and supermodel Cara also attended the star-studded bash with her rumored new girlfriend Ashley Benson. She shared numerous videos on her social media Story of her plunging into the giant pink ball pit at the party. And took countless pictures with other models and friends at the party's photo booth (would it even be a Kardashian party without one??)

16 Cara's Lady Love: Ashley Benson

Fueling the fire to the rumors that Delevingne is dating actress Ashley Benson, the two attended the party together, according to E! News and other tabloids.

Even though the two weren't actually seen cuddling up or posing in pictures together, this doesn't mean they weren't having a good time at the party.

Maybe they were just trying to keep it very low-key. Further proof is the fact that the pair was seen kissing and cuddling at London's Heathrow Airport just a few days after the epic birthday party. Apparently, the rumors were indeed true!

15 Social Media Star: Tammy Hembrow

Unfortunately, not everything went smoothly on Kylie's birthday. Life happens, you know. Basically, the birthday party ended with model Tammy Hembrow being transported to the hospital due to a sudden collapse.

The social media star definitely wasted no time to speak out about the incident and published a video on her Youtube channel where she reassured fans that everything is okay. “I've had a lot of concerned followers messaging me and asking if I'm just alright. So, I just want to clear that up and say yes, I'm okay,” she said.

She went on to explain that when she was in L.A. for the party she hadn't slept in about 30 hours and she should've focused on her physical well-being more. The social media mogul finished the video off by spreading a message on self-love. Just recently, however, Kylie unfollowed the model on social media. Ouch! She probably didn't appreciate the fact she almost ruined her 21st birthday party.

14 BBF Extraordinaire: Jordyn Woods

Known as Kylie's best friend (she appeared on countless episodes of KUWTK and Life Of Kylie!), Jordyn Woods definitely couldn't miss celebrating this important milestone with her BFF. The birthday girl's bestie went glam for dinner at the famed Italian restaurant wearing a gold short dress with stripes and matching shoes.

Kylie and Jordyn have been best friends and joined at the hip for years. “She was there before I was Kylie Jenner,” Kylie said during an episode of 'Life Of Kylie'.

Indeed, Jordyn was part of her support system before Travis and Stormi were even in the picture. Luckily, the beauty mogul didn't forget about that and kept her BFF closer than even at the party. She even decided to decorate the birthday cake with a pair of Barbie dolls that looked just like her and Jordyn partying like crazy!

13 Momager Kris' Plus One: Corey Gamble

Corey Gamble was probably one of the first people to be put on Kylie's guest list for her birthday party. Matter of fact, he attended the special occasion with none other than the coolest momager, Kris Jenner.

The two met a few years ago and even though their relationship seems to be the “on-again, off-again” kind, they attended countless events together. The 2018 Met Gala is one of the most recent and public ones.

The beauty mogul's birthday is not the first family event this guy has shown up to. For instance, he attended North West and Penelope Disick's epic unicorn birthday party in Calabasas in June. It must be cool to drop into Kardashian-style parties, right?

12 The One & Only Lord: Scott Disick

Longtime Kardashian-Jenner fans may also have been surprised by Scott Disick's appearance at the tv star's birthday party. In case you live under a rock and didn't know, Disick and Kourtney dated for nearly 10 years and share three children together.

He showed up without his current girlfriend Sofia Richie which itself started some rumors and speculations, but when he and Kourtney got caught up sitting next to each other at the table, Kim and Khloe went “fangirl” mode.

The two beauty moguls started joking on social media that the two were back together.

“Just like an old married couple on your phones!” Kim teased the former couple who were both sending text messages, while Khloe shared a video of the two, captioning the clip, “A girl can dream!”

Thanks to her video, now Kardashian fans can dream, too!

11 The Gang's All Here: Caitlyn Jenner

Indeed, as longtime Kardashian fans might already know, Caitlyn maintains a relationship with Kylie and Kendall, but she hasn't spoken to ex-wife Kris Jenner or any of her former stepchildren (Kim, Kourtney, Khloe, or Rob) in months.

However, all seemed peaceful during a snap shared by Kim, which panned many members of the family, including Caitlyn. “You guys, look! The whole family's here!” she said. Can we hope the feud is over?

And Caitlyn wasn't there alone, either. Various sources confirmed that Caitlyn's rumored girlfriend, Sophia Hutchins, also attended the party. “The two were inseparable while Kylie gave both of them a huge hug and was 'really happy' Caitlyn showed up,” a source told E! News.

10 Showstopping Beauty: Winnie Harlow

Winnie Harlow has made the effortless transition from an America's Next Top Model contestant to gliding down catwalks across the globe. And you can bet the Canadian model has collected a slew of A-list pals in the process, too. Among them, there's the beauty mogul and tv star Kylie Jenner.

Winnie definitely commanded attention as the layers of tassels on her one-piece caught the wind as she strutted along to Kylie Jenner's lavish 21st birthday at West Hollywood hotspot Delilah.

The Canadian star, 24, indeed, cut an incredibly glamorous figure in a white Meshki fringed jumpsuit and sky-high neutral heels.

Finally, she upped the glam factor with some glossy red lipstick. Kardashian-approved!

9 Funny Man: Dave Chappelle

The American stand-up comedian Dave Chappelle has been the protagonist in one of the most heart-touching moments of the entire birthday party. During the open bar party, indeed, the comedian and actor grabbed the mic and reportedly began crooning a Lauryn Hill song alongside Kylie's boyfriend Travis Scott. That's because when partygoers weren't singing impromptu karaoke, Scott's newly released album, 'ASTROWORLD', was booming from the nightclub's speakers.

“Everyone was laughing and loving it,” a source exclusively told E! News about Chappelle on the microphone. Since he's a professional comedian, we can pretty much assume he was one of the funniest guests to have around. Good choice, Kylie!

8 Caitlyn's Plus One: Sophia Hutchins

As we already mentioned, Caitlyn Jenner, 68, was dressed to the nines at daughter Kylie Jenner's 21st birthday party. And even though we don't think she was trying to steal the show, well, she sure came close. That's mostly due to the speculations that Caitlyn doesn't speak to any member of the Kardashian-Jenner family, with the exception of her daughters Kylie and Kendall.

But the drama would've been easily shut down if it weren't for the fact that the KUWTK star actually didn't attend the party on her own.

She indeed stepped out with her rumored girlfriend Sophia Hutchins, 22.

Of course, Kris Jenner was also in attendance at the bash. So, did things get awkward since they were forced into the same room? Who knows! There were probably enough people in attendance to keep Caitlyn and Kris away from any awkward interactions.

7 Team Khloe: Malika Haaq

Malika Haaq arrived at the epic birthday party with none less than Khloe and Kourtney Kardashian. Many loyal Kardashian friends might have already seen her on 'Keeping Up With The Kardashians' but in case you haven't, we'd like to introduce her a bit.

Malika Haqq is Khloe Kardashian's “professional best friend”. The pair has known each other since they were 15 and met through one of Malika's boyfriends when they were still in school.

This is what Khloe revealed on her blog: “Malika was dating one of my male best friends. He would always keep us apart because I am sure he knew we would just hit it off. One day we met and we did. Malika and Khadijah have been my best friends ever since.” This is such a romantic story to hear. Seems like friendship at first sight!

6 Kendall's Current Flame: Ben Simmons

Kylie Jenner's 21st birthday party was such a hot ticket that Jenner's closest family members attended even though it meant they'd have to share the room with their exes. It was the case of Kendall, for instance - who shared a quick awkward moment with her current flame Ben Simmons.

The young couple joined Kylie for the dinner at Craig's Restaurant, but unfortunately for them, there was an uninvited guest at a table nearby, Kendall's ex from last fall, Blake Griffin, who plays for the Detroit Pistons.

Apparently, Kendall and Ben just breezed past Blake without saying a word to him.

“They didn't interact at all,” a source revealed to E! News. Ugh! Awkward!

5 Another Basketball Beau: Jordan Clarkson

The Filipino-American basketball player Jordan Clarkson was also among the A-listers invited at the party. He currently plays for the Cleveland Cavaliers of the National Basketball Association (NBA).

Clarkson has been tied to the Kardashian family - and in particular to Kylie and Kendall - for quite some time now. Indeed, he didn't only attend Kylie's 21st birthday party, but Kendall's as well. It was even rumored that the two were dating at some point. Who knows, maybe the rumors about the basketball player and Kendall weren't so true after all - or it was a quick flirt and there's no bad blood anymore. Either way, there was clearly no embarrassment between them as they were enjoying the night's celebration together!

4 Basketball Star: Kevin Durant

In the Kardashian dating history, the girls are quite known for dating NBA basketball players (ever heard about The Kardashian curse?). This also means that many famous basketball players are part of the Kardashian inner circle. Among them, there's Kevin Durant - who was present at the birthday party.

In one of the most recent 'Keeping Up With The Kardashians' episodes, Kim and Kourtney were chatting about the fact Durant has supposedly referred to Kourtney as “cute”.

An innocent comment Kourtney didn't seem impressed by. And even though the two will probably never be tied to each other in romantic terms, the basketball player remains a close friend to the family. We'll probably keep seeing him attend numerous other parties in the future!

3 Basketball Wife: Draya Michele

Controversial socialite and tv personality, Draya Michele was on the birthday party's guest list. The former 'Basketball Wives' star is indeed a close friend of the Kardashian crew (remember when Kim sent her a sample of her new “Ride or Die” fragrance?) She even appeared on several episodes of 'Keeping Up With The Kardashians' and has been even spotted shopping with the family.

For most reality TV stars, fame lasts only as long as the show does. However, Draya Michele has proved herself to be an exception from the common lot as her career has grown manifold after she left her popular reality TV show 'Basketball Wives: LA'. She's launched three clothing lines since then and even starred in various movies. Perhaps her connections with the Kardashian family helped?

2 One Of Khloe's Biggest Fans: French Montana

Sean Combs' bestie and rapper, French Montana was present at the party and appeared to be having a good time (at least according to the various pictures and videos on social media).

As Kardashian fans might already know, he and Khloe were a bit of an item for more or less than a year in 2014.

Khloe and French later split in September, but it was reportedly amicable on both sides.

The rapper, in fact, commented the breakup with US Weekly saying that Khloe was “my baby forever,” and adding that there was “no bad blood”. And now we're sure about that because there were no awkward feelings in the air when the two ran into each other at the party.

1 The Ultimate Staze-Master: Kanye West

Married to none less than Kim Kardashian - with which he has three kids - Kanye West's presence at Kylie's 21st party was pretty much guaranteed. He showed up in several videos shared on social media from the night and appeared extremely happy (and we know how rare it is to see him smile! Ah!)

“Kanye and Kim were close and holding hands the entire night. They were super affectionate. Kanye didn't keep her out of sight and was super protective. They didn't leave each other's sides. Kim was grabbing him while dancing to the music and seemed super happy,” a source told E! News.
