Pete Doherty has reportedly told Paul McCartney that he’s definitely serious about getting off drugs during his current stint in rehab.

Pete was given special permission to leave his treatment programme at the Clouds rehab clinic in Wiltshire to interview the former Beatle for Observer Music Monthly magazine yesterday.

A source close to Pete told the Mirror: “Pete didn’t sleep the night before the interview just thinking about what he’d say to the legend when they actually came face to face. [But] they got on really well and Pete found Paul very supportive.”

“They had a real heart to heart - at times it was like a father talking to his son.”

“Pete promised Paul he was serious about getting clean, was through with the drugs, and said he never wanted to fall back into his dark days again.”

“They spoke about everything from music, other singers and even touched on the subject of women - but that was strictly between the two of them.”

The interview will be published next month.
