Jo Wood was an ''absent parent''.
The former model was married to Rolling Stones star Ronnie Wood for 26 years before divorcing in 2009 and she has admitted the couple's one-time ''out of control'' drug-fuelled lifestyle meant she often neglected their children.
In an interview with BBC Radio 4's 'Woman's Hour', she said: ''I was an after two o'clock mother. The nanny would do the morning, I'd do the afternoon. I was up until four, five every morning, get up at about two. My life was upside down for years. In the music business you stay up all night - maybe it's because of the drugs - and sleep all day.''
The 57-year-old mother revealed that she and Ronnie, 65, spent a ''crazy'' 18 months binging on drugs, including smoking cocaine with fellow celebrities in Los Angeles, while their kids were left at home.
She said: ''They didn't see what was going on. They just thought they had absent parents. I wish it hadn't happened. We were out of control for a year and a half.''
The couple raise four children together - Leah and Tyrone, as well as two sons from previous relationships, Jamie and Jesse - and Jo's desire to be a ''great mum'' helped her overcome her drug issues
She explained: ''I'm very lucky. I got to a point and turned round and said, 'I can't do this anymore.' I wanted to be a great mum and I knew I wasn't, so I stopped. I think I'm really a very fortunate person that I was able to. Ronnie carried on for three years and the more I saw him to do it, the more I thought, 'I'm never going to do that again.' ''
