Feel Old Yet? 20 Celebs Who Grew Up

Watching child stars grow up in Hollywood can be thrilling but also sobering. They start out as sweet, young and innocent little children in a film or show that we love and then we blink and they're strutting around town in an adult body doing adult things like paying bills and buying their own food. We wonder where the sweet innocent child went and what'll happen with the new adult replacement. And if we're the same age as the star, it's like watching our twin or best friend sprout before our eyes and morph into a successful grown up without us. In some ways, that's both easier and harder to deal with for some of us.

But questioning the universe and the future aside, we also get to watch these kids grow up in an admittedly harsh environment and somehow manage to thrive and come out on top as successful well-adjusted people (for the most part; there's always a few rotten eggs). Some of us even have kids the same age or close to the same as these youthful celebrities which can further drive home the point of how fleeting life is and how fast time flies. To further illustrate this fact, here are 20 young celebrities who just became legal adults.

20 Third One's The Charm

Willow Smith is the youngest child and only daughter of actor Will Smith and musician Jada Smith, making her an already famous name and giving her a boost of credibility in Hollywood. She has two famous older brothers and is busily making a name for herself as well. She first appeared in I Am Legend alongside her dad and has since appeared in several film productions, but her main focus is on music.

She's released several hit songs, beginning with Whip My Hair, and two albums with rumors of more to come. She and her brothers are also involved in charities and are youth ambassadors for Project Zambi which brings assistance to Zambian children who have been orphaned by AIDS. She is currently 17 years old with a bright future ahead of her.

19 Mackenzie Foy: Twilight Child Model Is Now 18 Years Old

Mackenzie Foy is best known for her breakout role of Renesmee Cullen in the final Twilight film. Prior to that, Mackenzie had started modeling at the age of three in print ads for Ralph Lauren, the Disney Company, Gap and others. She apparently did very well with modeling but decided to switch things up and take a different career path.

She started acting at the age of nine and since Twilight, has gone on in several different projects- including The Conjuring, Interstellar, Ernest and Celeste, The Little Prince, and is all set to play Clara in The Nutcracker and The Four Realms which comes out later this year. She is currently 18 years old and isn't locked into any long-term fields to hold her back from fully exploring every avenue open to her.

18 Landry Bender: The Up And Coming Actress Doesn't Look Her Age

Little known star Landry Bender is poised to launch herself into the spotlight. She's been around for a few years now, starring in mainly Disney productions such as Crash and Bernstein, The Sitter and Best Friends Whenever. She has had a recurring role on Fuller House and is currently involved in The Lion Guard on the Disney channel.

While these roles won't make her a big name overnight, they will build her skills and credibility, giving her an edge for when her elusive big break comes along. Where her future career lies is open to speculation right now, and she is ripe for a major breakout role any day now. She is currently 17 years old though it is arguable that she doesn't look her age at all.

17 Maisie Williams: GOT Goddess Grew Up Gorgeous

British actress Maisie Williams made her debut in 2011 in Game of Thrones as Arya Stark, a role she held for several years. Once the young newcomer was established there, she bounced over and guest starred as the immortal Ashildr in Doctor Who in 2015. Now die-hard fans of two massive fantasy dramas know who Maisie is and will probably follow her budding career with interest.

She's 20 now, not quite old enough to drink in America yet but still young enough to make us want to parent her. How her future career will turn out is an entirely open book. She could continue in the sci-fi fantasy genre or (which is more likely), she could branch out and test new waters for herself in literally any genre she chooses.

16 Camren Bicondova: 18 Year Old Catwoman On The Prowl

Camren Bicondova gained attention as a six-year-old dancer and pursued dance with a focus on funk and hip-hop styles, putting effort and hard work into her chosen career path for years. Her efforts paid off after her all-girl dance group appeared on America's Best Dance Crew in 2012 and placed second out of all the other contestants. In 2014 she landed the role of young Selina Kyle (Catwoman) on the hit show Gotham, where she is still a series regular. She's redefining the classic Catwoman that we've all become familiar with, and she's making the character her own. While she seems content for the moment, where this budding star will go in the future is anyone's guess. We'll all have fun watching her, at any rate. She will turn 19 in May.

15 Amandla Stenberg: This 19 Year Old Is Hungry For More

Amandla is a very outspoken feminist and identifies as non-binary or pansexual. She is currently 19 years old. Where she'll go from here is anyone's guess, but we'll be watching her and waiting to see how she'll change and influence the world around her with her fresh new ideas and looks.

14 Elle Fanning: Believe It Or Not But This Super Sister Is 19 Years Old

After getting out on her own and having her personal talent outside of her sister's shadow recognized, her career took off.

Elle starred in Daddy Day Care, The Door in the Floor and The Curious Case of Benjamin Button. As she grew older she starred opposite Angelina Jolie as Sleeping Beauty in Maleficent and has several upcoming films, including A Rainy Day In New York. What she'll do next will be eagerly anticipated by fans everywhere. She is currently 19 years old.

In 2015 Willow competed in the 20th season of Dancing With The Stars at the age of 14, the youngest competitor to appear on the show, beating out Zendaya for the record when she appeared at the age of 16 in the 16th season. Despite high scores, she and her partner were eliminated in the seventh round. Willow has lots of potential for a productive bright future. She is currently 17 years old.

12 Jackie Evancho: Billboard Topper

Jackie Evancho is a classical crossover singer who gained national attention at a young age and has been topping Billboard charts ever since with her seven albums and counting. She grew up Catholic with a supportive family and bounced between public school and cyber school as she grew her career.

And he starred in his first film, Middle School: The Worst Years of My Life.

He is currently 17 years old.

10 Kylie Jenner: Reality Star Is 20 Years Old And A Mama

Kylie Jenner may be a Kardashian but she's one of the slightly underrated (and definitely lesser known) members of that reality TV family and is still young enough to have plenty of untapped potential. She has already started her own line of cosmetics, a line of clothing with her sister Kendall, a popular mobile app, starred in her own spin-off series based on her life and has one child, making her a young single mom.

In 2017 she became the youngest person on the Forbes Celebrity 100 list. She and her sisters have been listed as the most influential teens in Times magazine in 2014 and 2015. With the power of her fans behind her, Kylie can certainly influence many for the better. She is currently 20 years old.

She has successfully made a name for herself in Hollywood and will probably continue to do so, but she is also being practical and giving herself a fall-back career option by pursuing a personal interest and studying law at UCLA currently. Her future is wide open and undetermined right now, which means she's free to take any road she likes and run with it. She is currently 20 years old.

8 Bella Thorne: This Rags To Riches Actress Is 20 Years Old

Actress Bella Thorne has climbed through the ranks of poverty to be where she is now, overcoming more odds in her way than some of her peers. She's survived abuse, struggled to find work as a child actor to help support her family and dyslexia.

Native Hawaiian Auli'i Cravalho made her breakout and debut role as Moana in the popular animated Disney film in 2016.

A talent scout convinced her to try after school was ended for the day.
