She speaks out about her first party experience was with her mum, Joanna Moore, when she was only a young girl.

The actress tells U.S. news show Access Hollywood, "We were living in a very kind of unsupervised place with my mom; she was really not doing well. She had had a very terrible bottom with speed and alcohol.

  "My mom... was with a 15-year-old boy... She was probably 35. That was a terrible situation.

  "There was a lot of alcohol around and there was a lot of other things... and I think what happened is there was a party and I just went around going, 'Hey, I'll drink some of that and I'll drink some of that...' and I just remember waking up on the bathroom floor, going, 'Where am I?'"
