Following the release of a very disturbing video showing Pete Doherty as he’s shooting up heroin again, the Babyshambles lead singer apologized to his remaining fans and said he was heading back to rehab.

"Peter sadly relapsed last week and is now looking to check himself back into a rehab clinic so that he can try to continue the hitherto excellent attempts he had made to break free of heroin," his record label, EMI, said in a statement.

The statement came shortly after a cell phone video posted on The Sun newspaper's website allegedly shows Doherty, Kate Moss' ex-girlfriend, as he’s preparing and injecting a shot of heroin into his right arm at his home in Wiltshire, England, just hours after flying home from the MTV European Music Awards.

The troubled singer probably lost count of times he’s been in rehab over the past year, only the worst part is that until recently, he claimed he was clean and appeared to be doing well.  

"It's not the first time he's injected since he was supposed to have gone clean. He may have got clean through rehab, but as soon as the temptation is put in front of him, he cannot help himself. It's so sad to see. He's been given so many chances and so many fresh starts and he just throws them all away," a source told the newspaper.

"His ongoing rehabilitation was a source of such pride to him that Peter and those closest to him thought that he was close to winning his personal battle with the drug," the statement continued adding that Doherty regarded the incident as "a stupid, stupid action for which I feel only shame."

He "would like to apologize to the medical staff, fans and well-wishers who have helped and encouraged his progress in fighting his addiction to heroin," the statement said.

Last month, Doherty, 28, completed a court-ordered drug treatment and as he vowed to stay away from drugs, an English court no longer considered necessary to monitor his promise. Earlier this week, he was quoted by various media reports as saying he’s going though a mourning period.

"It's hard work. I think I miss it a bit. ... I'm in mourning. I'm in mourning for an armful," he told British music site NME.com about his heroin addiction.

Asked by the magazine why he had managed to stay sober after his most recent stay in a rehab centre, he said: "I don't know what it is. I can't really put my finger on it, it's just the way it is, I'm afraid."

He also said that Babyshambles has been working really hard on a new material, and he’s anxious about getting on the road and playing those songs. The band’s forthcoming arena tour dates will not be affected by Doherty's return to rehab.
