George Michael has told how prison helped turn his life around.
The pop star served half of an eight-week sentence at London's Pentonville prison in 2010 after crashing his 4x4 while high on cannabis.
The Daily Mirror quoted him as saying: "I was put in with the paedophiles and the bullies.
"I didn't leave my cell very much in those few days."
But the newspaper said he told Radio 2 that just the possibility of being locked up made him seek help.
"It shook me out of my denial," he said. "Probably because there was a chance that I had to go to prison.
"From the day after that crash happened, I started in drug counselling, none of which I made public."
The former Wham! star, said it felt "fantastic" to be free and that his days of taking illegal drugs were behind him.
George, who is promoting a new album, Symphonica, said his time in jail inspired seven or eight songs and that he decided to end his relationship with Kenny Goss, his partner of 13 years.
