LOS ANGELES — Paris Hilton is being sued for allegedly wearing someone else's hair.

A company that manufactures hair extensions sued the socialite in Los Angeles on Wednesday, claiming she breached her contract to wear and promote their product.

The lawsuit claims Hilton agreed to wear Hairtech International Inc.'s extensions, but sported the fake locks of a competitor in 2008.

The lawsuit seeks US$35 million in damages -- 10 times what she was apparently paid under the contract.

The filing also claims Hilton missed a launch party for the hair extension line because she was serving a stint in jail in 2007.

Phone and email messages to Hilton's publicist Dawn Miller were not immediately returned.
