"She sat in the lobby for five hours and the concierge wouldn't let her up," Love told the New York Post. "Then she got in somehow and took all the cash in the house. It was only $600, but the (expletive) got away with a bunch of bank documents, too."
The alleged incident is the latest in a string of troubles Love has had in recent weeks.
Her trial on disorderly conduct and drug charges starts Friday in Los Angeles.

Love was also recently charged in New York for assaulting a man at a club with a microphone stand and she made headlines when she flashed her breasts at David Letterman in an appearance on his show.
