Bella -- born Annabella Avery Thorne -- has been working in movies and TV since she was 6, so it's refreshing to hear she's getting some proper mortifying teenage experiences. She candidly admits she's no stranger to embarrassing incidents: Her exploits include chipping a tooth playing paintball and getting her period on a date with her boyfriend.
"I'm not afraid to be myself," Thorne said. "I know that people are looking up to me, but I'm a teenager and I’m still going to make mistakes."
