Actress Tatum O'Neal was just six when she first tasted alcohol, while hanging out with her mum and her 15-year-old boyfriend.
The Paper Moon star has always been open about her troubled childhood, which she claims involved suicide attempts, drugs and booze, but revelations in a new book are sure to shock fans.
She recalls her first party experience was with her mum, Joanna Moore, when she was just a little 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?'"
'House' star Laurie received star number 2,593 on the Hollywood Walk of Fame this week.
The word 'jealous' doesn't even cover it right now.
