Babyshambles frontman Pete Doherty has reportedly kicked his long-standing habits, testing negative for drugs after spending time in a London-based rehab clinic.

The former Libertines singer was due to show up at West London Magistrates court yesterday to be sentenced for outstanding drug charges, but the case was adjourned. With Doherty's clean test results, it's expected he'll now be allowed to continue his rehab treatment.

"Pete's doing very, very well, and he wants to give himself a chance," Doherty's lawyer, Sean Curran, said.

"The court knows he's tested negative for drugs throughout his residential programme – that's six weeks now. The judge wants to see how he's keeping after the aftercare before he goes back to assess him."
