Rock musician Pete Doherty has been charged with possession of cocaine and heroin, police said Tuesday.

The 26-year-old frontman for the group Babyshambles was arrested Nov. 30 and formally charged Monday.

Doherty — whose on-off relationship with supermodel Kate Moss has made him a regular in the tabloids — was scheduled to appear Wednesday at Ealing Magistrates Court in west London, police said.

A Metropolitan Police spokeswoman refused to comment on reports that Doherty had interrupted a live gig at the Koko club in London on Monday night to invite his fans to join him in court.

Doherty was kicked out of his previous band, The Libertines, after failing to curb his publicly acknowledged drug problems.

Recently, Metropolitan Police Assistant Commissioner Tarique Ghaffur urged Moss to return home to Britain to answer questions over her alleged cocaine use. Moss, 31, lost valuable contracts with H&M, Burberry and Chanel after the Daily Mirror tabloid in September published pictures of her apparently using cocaine in a west London music studio where Doherty, then her boyfriend, was recording with the Babyshambles.
