A drug rehabilitation center has sued Courtney Love, claiming the singer has repeatedly refused to pay her $181,000 bill for her stay there 1 1/2 years ago.

The lawsuit, filed March 1 in Orange County Superior Court, said Love paid $10,000 when she entered Beau Monde, an oceanfront retreat in Newport Beach, in August 2005, but she still owes $181,286.

"Although demanded multiple times by plaintiff, orally and in writing, none of the balance stated has been paid," the lawsuit said.

Love's attorney, Howard Weitzman, said Friday the lawsuit "will be resolved to the satisfaction of all parties shortly."

A phone message left for Beau Monde's attorney was not immediately returned.

Love, 42, the widow of Nirvana singer Kurt Cobain and former frontwoman of the rock band Hole, has battled substance abuse and said in December she would remain committed to her sobriety.

In September 2005, Love was sentenced to 180 days at a drug treatment facility for violating probation in three misdemeanor cases -- one for illegal possession of painkillers, one for being under the influence of a controlled substance in public, and another for assault and battery.

Some of her time -- about 11 weeks -- was spent at Beau Monde, according to court documents.

The facility describes its mission on its Web site as helping "very successful, high profile individuals who are struggling with substance abuse, addictions, compulsive behavior, burnout, and other life/health issues." Guests are treated to gourmet meals, yoga and massages, and are allowed to leave the center for field trips such as golfing and hiking.

The three misdemeanor cases were dismissed by a judge who also terminated her probation.
