LOS ANGELES: American Express Co wants Courtney Love to leave home without it.

The financial services firm sued the musician in Los Angeles on Wednesday, alleging she owes more than $350,000 in unpaid charges and other fees on her AmEx Gold card.

The lawsuit, filed in U.S. District Court, seeks $352,059.67 for the unpaid balance, damages, attorney's fees and late charges, and says Love's charging privileges were suspended after she "failed and refused" to make payments.

Love's publicist said he had no immediate information on the suit, and had left a message with her attorney.

Love, the 44-year-old widow of late Nirvana frontman Kurt Cobain, is a litigation magnet. She was sued for libel in February by a fashion designer upset by comments Love had reportedly made about her on the micro-blogging Web site Twitter.

Last year, Love was sued for $1 million by an advisory firm seeking its share of proceeds from Love's partial sale of Nirvana's publishing catalog. The deal, covering such Nirvana tunes as "Smells Like Teen Spirit" and "Lithium," was reportedly worth $19.5 million. Cobain killed himself in 1994.
