Steve: (on why he became sober) Liv is possibly the biggest reason for me changing the way I lived. She is a dream daughter. When she was very young I wasn't sure whether I was the father but, by the time she was eight, I knew for sure. I saw my features in hers and I cried. I started seeing her a lot and I think her mother had alluded to the fact I was her dad. I just said to her, 'Liv, there's something I want to tell you. I'm your Daddy.' It was one of the most emotional moments of my life and I just stood there crying like a baby while she shouted, 'I knew it, I knew it.' I love her more than anything and have a great relationship with her. We can talk about anything.
