Hairtech International Inc. is seeking $35 million in damages, which is 10 times what she was paid under her contract, according to the AP. The fraud and breach-of-contract suit also cites Hilton's partying for going against its marketing campaign.

Hairtech is also annoyed Hilton, 29, missed the line's 2007 launch party because she was serving 23 days in jail for driving twice on a suspended license while on probation for reckless driving. The company says it lost $6.6 million on Hilton's absence from the fete.

This isn't her first endorsement deal that has landed her in hot water.

In 2008, producers of Pledge This! sued Hilton, claiming she didn't fulfill her promotional responsibilities. Judges are still determining if she'll have to return any of her $1 million fee to filmmakers.

Update: Attorneys for the star tell UsMagazine.com: "There is no merit whatsoever to any of these claims. We will pursue all of our defenses vigorously and any potential counter claims."
