London ? Pete Doherty, the ex-boyfriend of supermodel Kate Moss, pleaded guilty Friday to possession of heroin, crack cocaine, morphine and marijuana.

Doherty, 26, was freed on bail until sentencing Feb. 8.

Police said the charges stemmed from Doherty’s arrest Dec. 4 in east London, one of a string of drug busts for the lead singer of the band Babyshambles.

Doherty also was arrested Nov. 30 and charged with possession of cocaine and heroin. He pleaded guilty last week and was released on bail.

He was stopped by police a week ago while driving through east London and again arrested on suspicion of possessing drugs. He was released on bail and ordered to return to a police station for questioning Feb. 2.
