Courtney Love's trial for illegal possession of painkillers has been postponed until 3 November because of scheduling issues.
Ms Love told reporters she was "scared"
Ms Love, 40, is also facing financial trouble as three creditors accused the singer of not paying her bills.
A travel agency said she owes it $50,000 and her New York apartment board claims she has not paid charges on her SoHo property.
She also allegedly owes over $35,000 in taxes on her employees in Los Angeles.
Ms Love's lawyer, Scott Tulman, said he was unaware of any financial problems she had.
The singer also faces two separate assault cases - one for allegedly attacking a woman with a bottle in Los Angeles in April, and another for allegedly throwing a microphone stand which injured a man in the crowd at a New York.
She pleaded innocent in August to charges of assault relating to the Los Angeles incident.
A preliminary hearing was set for 7 October. Ms Love appeared composed, but told waiting reporters: "I'm scared."
Mr Tulman filed a motion in the New York State Supreme Court on Wednesday seeking the dismissal of assault and reckless endangerment charges related to the microphone incident, which is said to have taken place after a TV appearance in March.
