At some point, we have all wondered what happened to some of the child stars we grew up with on TV and radio, and the online search results can often be quite surprising.

It's the harsh reality of showbiz that not every child star is guaranteed a successful career. Some former child stars even got fed up with fame while they were still teenagers and decided to retire from acting altogether, in order to purse completely different career paths.

Perhaps the most surprising thing is that many former stars claim their iconic childhood roles have damaged their careers, as they've become pigeonholed - so they won't get hired due to stereotyping. Here's a mix of child stars from the early 2000s who either made it, failed spectacularly, or just simply quit showbusiness altogether.

20 Jake Thomas

Jake Thomas may have been Lizzie McGuire's annoying younger brother, but he was more than just a sidekick. After Lizzie McGuire wrapped in 2004, Thomas appeared in another Disney Channel show, Cory in the House. He's still acting, but he's also developed quite a talent for working behind the camera, and has even pursued his educational goals, graduating from college in 2018.

19 Alyson Stoner

Whether it was Sally in Mike’s Super Short Show, Max in The Suite Life of Zack & Cody, or Caitlyn Gellar in the Camp Rock series, Stoner mostly portrayed tomboys. Luckily, she doesn't look like a tomboy anymore. Alyson has appeared in the Step Up franchise and performed voice acting for animated shows. She's even launched her own YouTube channel where she shares dance videos, music covers, and personal Vlog style videos.

18 Freddie Highmore

Freddie Highmore has been racking up awards and nominations his entire career and built a reputation for himself starring in movies like Finding Neverland and Charlie and the Chocolate Factory. His role in Bates Hotel as a young adult showed the depth of his range, and his latest hit show, The Good Doctor, proves that Highmore is truly one of the great actors of his generation.

17 Taylor Momsen

Taylor Momsen captured everyone's hearts as little Cindy Lou Who in How the Grinch Stole Christmas. For a while, Momsen kept acting, landed a major role on the teen drama Gossip Girl, then her band, The Pretty Reckless, took off and made her a bonafide rock star. Today, she focuses on her music and gets uncomfortable talking about her Gossip Girl days.

16 Jake T. Austin

Wizards of Waverly Place star Jake T. Austin had actually been in show business for years before landing a role on the show.

School was back in session when Kevin Clark reunited with his onscreen teacher Jack Black. The child star played drummer Freddy, aka Spazzy McGee, in the 2003 comedy School of Rock.
