But now Villegas is ready to enter a more adult world, in her professional career and in her style. She tells us the reason she recently went blonde was to finally look a little older.

"My hair's always been dark brown," Villegas said. "I went through a couple of stages where I dyed the tips red, blue and purple but everyone was always like, 'Oh, you look 15! You look so young, how old are you?' So I [wondered] what can I do to look my age? I know looking young is cool but�I don't always want to be cute."

Villegas says the change made her not only feel older, but feel like a new person. The former child star told us she didn't really start wearing make up until she was 14 or 15, despite her life on the set, and that now, as an artist with her own single, "That's Me Right There" featuring Kendrick Lamar, she's working with her hair and make up artist to learn the tricks of the trade. Her other favorite place to pick up tricks? Those 15 second Instagram beauty videos.
