Smith was 10 years old when her single "Whip My Hair" hit No. 11 on the Billboard Hot 100 and she toured with Justin Bieber, which she describes as "overwhelming but amazing." She has since cut her whippable braids, but that wasn't some teenage act of defiance. "Shaving my hair made my inner light grow and shine even more," she says. "I really like who I'm evolving to be." Music continues to be a go-to form of expression for the teenager who quietly posts woozy new electro jams to her SoundCloud account, and plans to tour this year.
