5. Shia LaBeouf
He starred in Even Stevens and played a mischievous child, who was always getting on his older sister’s nerves. He went through a route for becoming a musician but failed. Then he ended up acting in Hollywood blockbusters franchises like Transformers and films like Disturbia.
6. Ashley Tisdale
Remember Maddie from Suite Life of Zack and Cody? She was much older than most of the teens on this list when she got her start with Disney—she was 19 years old when she joined the show. When the show ended she didn’t leave Disney and rather joined High School Musical movies. Then in 2011, she left the channel for further acting in Fabulous Adventure.
7. Jemma-Mckenzie-Brown
If you’re a fan of the High School Musical series, you definitely know who Jemma McKenzie-Brown is. That was way back in 2008 when she was just about 14. It seemed like she had a promising acting career ahead of her. So, where’d she go? Well, she quit acting altogether (even turning down a spot in High School Musical 4, reportedly) and is now a fitness trainer at Barry’s Bootcamp.
