It seems like Barney & Friends is just producing all of the young stars! Selena Gomez starred on the show as Gianna, which is where she met Demi Lovato. Like so many other child actors, Gomez also got a great start at Disney. She had a recurring role on the series Hannah Montana as pop star, Mikayla, which she played alongside Miley Cyrus, who had the lead role.
Fast forward a few years and Gomez is now one of the biggest celebrities in the world. After moving away from acting gigs, she developed a thriving career as a pop star and is in an on again/off again relationship with one of the other biggest celebrities in the world, Justin Bieber. She really has come a long way, but she has worked hard and totally deserves it!
