Richie Sambora has revealed his daughter inspired him to go to rehab and get sober.
He told Classic Rock Magazine: ''She (Ava) was like an angel to me, man ... that was the catalyst for me actually getting sober.''
The 53-year-old musician continued: ''Luckily I wasn't that guy who lost his band, his family, his house and his job. I wasn't a victim.''
His first spell in rehab was in 2007, after the death of his father Adam and amidst the breakdown of his marriage to actress Heather.
Richie blames being in a rock band for his substance abuse problems, which included heavy drinking and eventually a reliance on painkillers.
He explained: ''I was in a rock 'n' roll band! Drinking was a badge of honour.''
His prescription drug addiction started when he broke his arm just two weeks before Bon Jovi were due to start a stadium tour in the mid-2000s.
He recalled: ''I was in a bad way with my arm and I needed to get through it.''
Enlisting the help of ''various physical therapists,'' Richie began taking ''a bunch of pain pills,'' something he'd never done before.
He admitted: ''I've conquered a lot of stuff in my life, but when I tried to get off those things I couldn't do it ... I was drinking too, which makes it double bad.''
Despite his addictions, Richie thinks rehab isn't as bad as it's perceived and is actually a good experience.
He said: ''People look at rehab as a bad thing ... I looked at it as an opportunity to do something positive for myself.''
