The footwear group slapped the hotel heiress with a USD 2 million breach-of-contract suit on May 17 in Manhattan federal court, reported the New York Post.
The counterclaim demands Hilton refund USD 2 million in royalties Antebi has paid the hotel heiress since it began selling her footwear products in 2007 and other money damages.
It alleges that Hilton back-stabbed Antebi by tapping a rival footwear company, Retouch, last year to license a competing footwear line, 'Parisian Parc' in violation of a contract agreement with Antebi.
The counterclaim is in response to Hilton socking Antebi with a USD 1 million lawsuit last month alleging she was unlawfully squeezed out of royalties after the firm allegedly failed to honor its licensing agreement.
Antebi claims Hilton broke her agreement first. The new filing also seeks Hilton's suit be dismissed.
