In an interview with the British newspaper The Sun, the 23-year-old actress said problems with her father led her to depend on drugs to a "terrifying" degree and subsequently, check into rehab three times. "I tried to mask my problems with alcohol, cocaine and mind-altering substances," she said, revealing that she abused Ambien in addition to cocaine and alcohol. "Now I'm in a place where I don't need to use anything and I can feel emotions because I choose to." (Flynet)
