16 Celeb Wedding Guests Who Stole The Spotlight (+ 4 Who Look Like They Didn't Even Try)

When we think of a celebrity wedding, we assume that there is no way that the bride will be upstaged by anyone. Well it definitely happens and more times than we realize. There are times when the bride looks like she's fading into the background compared to her bridal party. We have seen over the years some celebrity weddings where the bride's spotlight was stolen by a bridesmaid, guest, or even their own sister.

Some can't even help it because they have a larger-than-life personality or they are just used to being the queen of the world. Sometimes A-listers can't help but take centerstage, they have trouble just blending in.

There are also the guests that show up to a wedding so underdressed that you wonder why they bothered at all. We couldn't imagine attending a wedding not looking our best, but it happens often. Check out these 15 sisters of the bride who stole the show (+ 5 who were underdressed/who look like they didn't bother).

20 Stole The Show: Beyoncé Showed She Was Queen

Solange Knowles chose very simple and chic styles for her wedding dresses so she made it easy for Beyoncé to steal the show. Everyone wore white so it almost looked like Beyoncé was on the way to her own wedding. Her dress was form-fitting and foxy and she made it clear that she was still queen regardless of whose wedding she was at. Beyoncé interviewed her sister for Glamour magazine and stated, "I'm so happy to interview you because, clearly, I'm your biggest fan and I'm super proud of you." She later added, "I remember thinking, 'My little sister is going to be something super special,' because you always seemed to know what you wanted."

19 Stole The Show: Emma Roberts Is Glamorously Elegant

When Emma Roberts was honored of being a bridesmaid at her friend's wedding, she probably didn't expect to look as beautiful as this. The bride faded into the background completely when Roberts stepped out. She has the same Hollywood presence that her aunt Julia has and she looks stunning in this bridesmaid dress. She was one of ten bridesmaids that were standing up in the wedding party, but not one looked more elegant or chic as Roberts did. Her dress has a vintage flair to it that is perfection.

18 Stole The Show: Taylor Swift In Burgundy

We think it would be hard not to steal the show if you are Taylor Swift and you are a bridesmaid in a wedding. She is after all one of the most talked about artists in the industry right now. She stood in the bridal party shortly after she released her single "Look What You Made Me Do." It was her first public appearance at the time since her release. She also stole the show when it came to her bridesmaid speech which was particularly raunchy. A video of the speech was leaked and you can see the couple laughing hysterically.

17 Stole The Show: Cara Delevingne Stole Poppy's Spotlight

It was Poppy Delevingne that was getting married to James Cook in 2014, but all eyes were on her younger sister, Cara. It didn't seem to matter that Poppy is a stunning woman or the fact that she wore a Chanel gown, people were more focused on how amazing Cara looked. Cara wore an elegant white dress by a French designer and had a chic up-do. It's just one of those times where it sucks to have a supermodel for a sister.

16 Didn't Bother: Jaden Smith At Kim's Wedding

If this isn't a cry for help or a need for attention, then we are not sure what it is. It's definitely embarrassing and we can't believe that Jaden Smith thought it was appropriate to show up at a wedding in a white Batman suit. What was he thinking? If it wasn't for the fact that he's Will Smith's son, he probably would have been thrown out the wedding.

Jaden explained the need to dress ridiculously by stating that he "felt as though he needed to protect everyone there and needed the proper gear to do so," according to the Daily Mail.

15 Stole The Show: Alessandra Ambrosio Was Breathtaking

When you invite a Victoria's Secret supermodel to be a bridesmaid in your wedding, you are really taking a risk that you might be upstaged. If you see the whole photo album, you will see Alessandra dancing and pretty much stealing the show every way that she can. She wore a long gown with a long slit that showed off her fantastic legs. The model did a great job of upstaging her friend and being the most beautiful woman in the room. It was like the photographer followed just her the entire day.

14 Stole The Show: Rihanna Took Centerstage

Rihanna put on a lilac dress to stand in the wedding of her assistant Jennifer Morales. That's one lucky assistant. Although Rihanna looks cool and collected in this photo, there are many shots that show the Rihanna that we truly know. In most of the wedding photos, she took the center spot in the photo proving that she believes she should always be the center of attention. The wedding was on the beach and you could almost see Rihanna struggling to not be in every single picture.

13 Stole The Show: Margot Robbie Was A Vision

This is another case of the bride choosing a really plain dress and the bridesmaids shining instead. Margot Robbie looked amazing in this beach-themed dress and she definitely outshined the bride whether she meant to or not. She is effortlessly beautiful in the wedding photos and it's like she's in a movie and not at her friend's wedding. This dress could have easily passed for a wedding dress and it was so much more elegant than the bride's dress.

12 Stole The Show: Keira Knightley Was A Vision

It probably has a lot to do with what the bride is wearing but, in this case, Keira looked so much lovelier than the bride did. In this case, the bride's dress seems old and frumpy. It's a dress that could easily be straight from the '50s. This was the wedding of her brother Caleb and the bride would be her now sister-in-law. The bride is actually designer Kerry Nixon, but she was completely outshined by the bridesmaid who popped in a plum-colored short dress.

11 Didn't Bother: Ashley Graham Wore Pants

Seriously on a scale of 1 to 10, how steaming mad would you be if your sister showed up to your wedding looking like this? Don't get us wrong, this is a cool and foxy outfit for a night on the town with your friends, but for a wedding, it's borderline insulting to show up looking like that. The wedding picture between these two sisters seems awkward because Ashley is so underdressed. We get it, you're a model but that doesn't mean you should go to a wedding thinking you can wear anything you feel like.

10 Stole The Show: Susan Sarandon Caught Everyone's Eye

Susan Sarandon and Eva Amurri had sort of matching dresses for the wedding which is actually a really cute idea. They look amazing together but without trying, it looks as if Susan has stolen the show from her daughter. Susan is an icon in the industry and she looks so glamorous in this photo. It's likely that Susan has always had shows that were really hard to fill for Ava. She has had nowhere near the success that her mother has had in the industry. We are betting that a lot of people were fawning over Susan and this gorgeous dress.

9 Stole The Show: Kate Bosworth Was A Bombshell

How iconic does Kate Bosworth look in this shoulder-bearing black dress? The bride who is a friend of Bosworth's went with untraditional colors for the bridesmaids, but they all look elegant and classy. Bosworth looked like she belonged in a fashion magazine and although the bride looked stunning, it was hard not to just stare at Bosworth the whole time. The wedding was held in Sydney, Australia and the sun was shining brightly on everyone that day.

8 Stole The Show: Lauren Conrad Took Control

This is just another great example of how a bridesmaid can outshine a bride and she seems to be doing it flawlessly. Lauren Conrad wore this elegant baby blue dress which completely outshined the bride who wore a simple black dress for her wedding. Conrad is beautiful and has a family now as she juggles her busy life as a designer and blogger. She's looking better than ever since her days on The Hills and she has certainly made a career for herself in Hollywood.

7 Stole The Show: Sofia Vergara Shined In Yellow

It's not hard for Sofia Vergara to outshine anyone wherever she goes. She can make eating pizza look like the most glamorous thing in the world. Whether she wanted to or not, she managed to steal the show at her friend's wedding where she acted as the maid of honor. She is an absolute bombshell in this dress and she probably had every eye in the room on her. There is a photo of her on social media in this dress where she is eating the wedding cake and still looking like a total babe.

6 Didn't Bother: Jessica Alba And Her Understated Dress

We're actually surprised that a celebrity would go to a wedding looking so underdressed. The dress is beautiful, but it's something we would think she would wear to brunch with the ladies. It's also a midriff-baring outfit which just seems inappropriate for a wedding. It's a floor-length skirt, but it's one of the more casual options we have seen at a wedding. She looks great in the casual dress, but we think she could have tried much harder for a friend's wedding.

5 Stole The Show: Rosie Huntington Was All Glam

Anyone that dresses like this for a wedding is sure to steal the show form the bride. Rosie Huntington wore this stunning gown to singer Leah Wood's wedding in 2008. It was a star-studded affair with guests such as Jade Jagger and Kate Moss, so we can just imagine what a fashion event this was. When you are going to a wedding, however, you should probably not be the most elegant person in the room. This dress could easily pass off as the wedding gown itself.

4 Stole The Show: Emily Blunt Was Eye-Catching In Blue

Emily Blunt could steal anyone's thunder in this insanely gorgeous blue dress. This dress is proof that she takes attending a celebrity wedding very seriously and she's not going to just wear anything. She wore this beautiful dress to George Clooney and Amal's wedding in 2014. If you look at the other pictures of blunt at the wedding, you can see that she is turning heads wherever she goes. The dress is fabulous and it creates such an attractive silhouette.

3 Stole The Show: Eva Longoria Is Soft And Elegant In This Hue

Eva Longoria has been a bridesmaid for a few of her friend's weddings and she always looks stunning. She is especially beautiful in this pastel number and it's hard to believe that she didn't steal the whole show in this dress. She had a moment at this particular wedding when a friend's hair got caught in the belt of the dress. We're not sure how that sort of thing happens, but it made for a funny story on social media.

2 Stole The Show: Florence Welch Went Custom

You might think that it would just be the bride that decided to have a custom outfit for her wedding, but you thought wrong. When vocalist Florence Welch decided to go to a friend's wedding, she wanted a custom outfit that would drop jaws and that's exactly what she got. You don't see too many outfits like this one at weddings, but it likely stole the show. The outfit was created by designer Hermione de Paula and we can be grateful that she didn't decide to have it done in white.

1 Didn't Bother: James Van Der Beek Looks Like He's Going To Prom

Ever since he starred on the hit TV show Dawson's Creek, James Van Der Beek has been many a girl's crushes. He looks exactly the same, so he probably still is. We were really disappointed in the suit that James wore to the wedding because it was so plain and it really made him just fade into the background. He has a gorgeous wife named Kimberly and even she chose a dress that was really plain. This photo could easily be their prom photo for all the effort that was put into their outfits.
