A bunch of huge names were only kids when they stepped into the spotlight, and it’s pretty crazy to think that they’re all grown up now!

Mara Wilson, for example, starred in the flick Matilda as the title character, and now — more than 20 years later — she’s completely transformed herself into one of Hollywood’s biggest stars. When reflecting on her life as a child star, the actress told Collider in March 2021 that she’s “glad” she started so young.

“I had wonderful experiences that I never would have been able to have. It definitely meant that I had an audience for what I wanted to start writing and performing more, as an adult, that I wouldn’t have had otherwise,” she explained. “I also do feel like that level of fame, for anybody, is not a natural thing and can be very dangerous for kids.”

During the same interview, the actress also got real about her appearance in the HBO documentary, Showbiz Kids. “I really loved that it was child actors being asked about their experiences and it was a former child actor making it because I feel like, a lot of times, people don’t quite understand our situation and the framing of it,” she said. “It felt mostly reassuring and cathartic. It made me realize that my experiences were not universal, but that I was not alone in them. That was something that really meant a lot to me.”

It turns out, she’s not the only one whose stayed in the spotlight after their younger years. Yep, a bunch of celebrities that we grew up watching are all grown up themselves now, and boy, do they look different.
