Supermodel and ex-drug addict Kate Moss has offered to pay for Pete Doherty's rehabilitation program - providing that he sees it through to the end.

Following the publication of photos depicting the Babyshambles frontman allegedly injecting a fan with heroin, Moss has apparently issued the ultimatum to her ex-lover.

A source said, "She's told Pete it's his last chance. She's offered to pay for his treatment on the condition he sees it through and gets clean."

The former Libertines star will apparently check into a £1,000-per-night clinic in London after returning from a trip to Amsterdam.
