Have You Seen These 13 Stars In Their First Acting Roles?

Today, Selena Gomez is one of the biggest celebs in the world, but back in 2002, people simply knew her as Gianna from Barney & Friends. And she isn't the only star who got an early start! Check out 12 of our favorite clips of our favs before they were stars.

Selena Gomez and Demi Lovato both got their start on Barney & Friends playing Gianna and Angela. Clearly it put them both on the road to Disney stardom!

One of Kendall Schmidt's earlier roles was on Frasier as a younger version of the title character. Baby Frasier strikes a hard bargain!

In 2005, Lucy Hale played Amy on Ned's Declassified School Survival Guide. Her onscreen relationships are still just as complicated.

On The O.C., Bella Thorne played a younger version of Autumn Reeser's character, Taylor Townsend. Bella has come a long way from playing the outcast.

Kristen Stewart appears briefly in The Thirteenth Year. 

Shailene Woodley also got her start on The O.C. as little sister to Mischa Barton's character, Marissa.

If you blink, you'll miss Jennifer Lawrence in this clip from Monk playing a school mascot.

This short video from Miracle Dogs isn't Josh Hutcherson's first acting role, but it DOES include puppies and slightly flawed logic concerning dog magic.

In one of Victoria Justice's first roles on Gilmore Girls, she got to wear Spock ears and sass Melissa McCarthy. 

Tomorrowland's Britt Robertson got to play a mini pink Power Ranger in Power Rangers: Time Force back in 2001.

Laura Marano plays a snarky student in a 2004 episode of Joan of Arcadia, and the kid next to her kind of looks like a tiny Ross Lynch!

Olivia Holt played the super inquisitive Claire in Black and Blue in 2009, and she is still just as adorable.
