LOS ANGELES (AP) – Troubled rock star Courtney Love got a bench warrant for her 40th birthday when she failed to appear in court Friday for arraignment on an assault charge.

Love was in New York City and was confused about whether she was required to be in the California courtroom, defense lawyer Michael Rosenstein said.

Court Commissioner Dennis E. Mulcahy said there was no excuse for her failure to appear. He said she forfeited her $55,000 bail and he set a new bail of $150,000.

Love, former lead singer of the band Hole, has coast-to-coast legal troubles and has had to reschedule a summer tour to support her new album, “America’s Sweetheart.”

Last month she was scolded by a judge when she showed up more than five hours late to a Manhattan court for a hearing on charges of assault and reckless endangerment for allegedly hitting a fan with a microphone stand in the East Village in March. She’s due back there Sept. 7.

Love was supposed to have been arraigned in Los Angeles on a charge of assault with a deadly weapon for allegedly attacking a 32-year-old woman with a liquor bottle.

The charge involves an April 25 incident at the home of former manager and ex-boyfriend Jim Barber.

Love, also was charged in two cases stemming from encounters with police on one night last October.

Authorities said cocaine and other opiates were found in Love’s system after she was arrested for allegedly trying to break into Barber’s home. She pleaded guilty to a misdemeanor drug charge and agreed to enter a drug rehabilitation program.

She is also facing a felony case in Beverly Hills Superior Court for alleged illegal possession of prescription painkillers. Love allegedly gave officers a small bag of pills after they responded to a call from her home hours after her initial October arrest.
