LONDON (AP) - Pete Doherty was released from a London jail Tuesday after serving a partial sentence for breaking his probation. The Babyshambles frontman had served 29 days of a 14-week sentence. It wasn't immediately clear why he was released early.

Doherty's drug use has frequently landed him in court. Last year, he pleaded guilty to possession of crack cocaine, heroin, ketamine and cannabis, as well as a variety of driving offenses. His recent jail sentence came after the 28-year-old singer was reportedly late for several probation appointments.

Doherty is best known as the on-off boyfriend of model Kate Moss.
