On Sunday, the 20-year-old actress announced her support for the anti-harassment movement, Time's Up, by sharing her own painful experience. "I was sexually abused and physically [abused] growing up from the day I can remember till I was 14 when I finally had the courage to lock my door at night and sit by it," she wrote. "All damn night. Waiting for someone to take advantage of my life again. Over and over I waited for it to stop and finally it did. But some of us aren't as lucky to get out alive. Please today stand up for every soul Mistreated. #timesup."
The Famous in Love star has always been good about being candid with her fans, but admitted to ET last January that the negative comments and rumors do get to her.
"People think it doesn't hurt but let me tell you, it does hurt! It doesn’t feel good to read this sh** about yourself online even when you know it's not true," she exclaimed. "That's always the worst part, when it's not true. If it's true, you're kind of just like, 'OK, you're calling me out. This is true.'"
