Courtney Love is facing a legal battle with American Express over the credit card company's claims she has racked up more than $350,000 in unpaid charges.

The firm filed suit against Love in the U.S. District Court on Wednesday, demanding the rocker pay off the staggering debt on her Gold card. The former Hole frontwoman had her plastic privileges suspended after she "failed and refused" to clear the balance, according to the lawsuit.

Love has been continuously struggling with her finances in recent years - it emerged in April she had hired a team of private investigators to reclaim the millions of dollars she alleged were stolen from her late husband Kurt Cobain's estate.

And just last year, Love was sued for $1 million by London & Co., an accounting firm which charged the star had failed to pay them profits from the sale of Cobain's share of the Nirvana publishing catalogue.

A spokesperson for Love was unavailable for comment as WENN went to press.
