The Hello singer tells British newsman Piers Morgan his nine-year marriage to former mistress Diana Alexander fell apart in 2003 when he turned his back on a life of luxury and found himself recording new music.

Richie says, "I made a promise that I would not go back to work. One day I knew I was in trouble because I just happened to stumble back into the recording studio. Over."

In his candid chat with Morgan, which airs as part of U.K. show Piers Morgan's Life Stories on Friday (04Sep15), he also recalls shutting down a tour in Europe in 2005 to enter rehab with his troubled daughter Nicole after she was arrested for possession of heroin.

He adds, "That’s a fairly cataclysmic thing for any father to have to watch his beautiful, young daughter go through.

"I got a phone call and she said, 'Dad, I need help...' And I said, 'I am with you', and I cancelled the tour. I said, 'Me and your mother', who didn’t get along that well, 'Me and your mother are checking into rehab with you'."
