Rock star Courtney Love was hospitalized in New York on Friday after a warrant was issued for her arrest when she failed to appear in a Los Angeles court for arraignment on an assault charge, her attorney said.

"She is hospitalized in New York area hospital," attorney Michael Rosenstein said.

"It is not a suicide attempt, not drug-related, not drug-overdose related," he said. "It's a gynecological medical condition for which she is receiving treatment. This is all thirdhand, I have not spoken with her since last night, when she complained of medical problems, had not seen doctor and as a result the situation was exacerbated."

Earlier, Rosenstein had told a Los Angeles court that Love was in New York City and was confused about whether she was required to be in Los Angeles.

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.

The former lead singer of the band Hole has coast-to-coast legal troubles and has had to reschedule a summer tour that was intended to support her new album, "America's Sweetheart (search)." Friday was her 40th birthday.

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, the widow of Nirvana singer Kurt Cobain (search), 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 in October for allegedly trying to break into Barber's home. She pleaded guilty last month 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 (search) for alleged illegal possession 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.
