Pete DohertyPete Doherty has checked himself into a rehab clinic in Portugal to try to beat his drug addiction.

Pete is trying a sleep cure - where he is kept asleep for a week - to get over the initial withdrawal cravings.

A friend has revealed: “He’s tried everything but it’s been pretty halfhearted.”

“[Kate Moss] paid for his last implant, which is meant to stop heroin having an effect, and she has offered to fork out again. She’s really proud of him and has assured him she’s behind him every step of the way.”

“He’s being ‘put under’ for six or seven days so he won’t have to do cold turkey.”

Pete has been threatened with jail by the judge in charge of his supervision order if he doesn’t give up drugs.
