Opera singer Katherine Jenkins has revealed that she experimented with drugs, including cocaine, ecstasy and cannabis, before she became famous.
The 28-year-old Welsh singer told The Mail on Sunday that she fell in with a "bad crowd" when she first moved to London.
Jenkins said: "I was young and silly and never really thought about the consequences."
"I just liked going out with friends, getting drunk on too many Malibus and Cokes, and then someone would produce some drugs and occasionally I would take some."
"I was hanging around with a bad crowd. I was very trusting, and keen to please. I never really enjoyed taking drugs, it made me fit in better."
The singer confessed to taking cocaine on up to seven occasions, ecstasy pills maybe half a dozen times and cannabis cakes seven or eight times.
She said that cocaine left her feeling "absolutely terrible" with "the worst hangover in the world", while ecstasy made her "so depressed".
Jenkins said that she stopped taking drugs when she secured a record deal.
"I knew in that moment that I had to stop taking drugs. I'd been given this amazing opportunity and I just couldn't let myself mess it all up for the sake of cocaine or ecstasy," she said.
The singer said that her past drug use made her "feel so ashamed" because the drugs were "dangerous and destroy lives".
