Mark Owen has confessed he has been battling alcohol addiction for at least a decade.
The Take That singer, who apologised for cheating on his wife Emma with as many as 10 women, called himself "a prat" and further admitted being a heavy cannabis user.
"I have had issues for a long time. I've drunk for the last 10 years and it got to a bad point," the Mirror quoted him as saying.
The 38-year-old dad-of-two added: "I want to make it absolutely clear I am not using the drink as an excuse. I've been living with the guilt. Maybe the drink was my way of dealing with the guilt."
