Hilton was sued Wednesday in Los Angeles for allegedly breaching a contract to promote and wear hair extensions manufactured by Hairtech International Inc. The company is seeking $35 million in damages - 10 times what it paid Hilton for her endorsement.
Spokeswoman Dawn Miller said in a statement released Thursday that Hilton's attorneys state, "There is no merit whatsoever to any of these claims. We will pursue all of our defenses vigorously and any potential counter claims."
Hairtech claimed Hilton did not wear the company's extensions as promised and missed a launch party in 2007 because she was in jail. They claim the damages from the missed appearance were at least $6.6 million.
Hilton served 23 days in 2007 after she was caught driving twice on a suspended license while on probation for reckless driving.
A jury or judge will decide whether Hilton owes Hairtech any money if the case goes to trial.
