Socialite Paris Hilton is being sued for $2 million by a footwear company that claims she has breached her licensing agreement with them.

A breach-of-contract lawsuit against the socialite and businesswoman has been launched in New York by Antebi Footwear Group, which claims she went back on a business deal with them and even promoted rival product Parisian Parc footwear line on social media, reports contactmusic.com.

According to the New York Post newspaper, the lawsuit states: "(Paris Hilton Entertainment) breached its covenant of good faith and fair dealing to Antebi by means of its aforesaid intentional and malicious acts and by destroying and injuring Antebi's rights to receive the fruits of its relationship with PHE and those rights granted pursuant to the exclusive licensing agreements."

The company's move is in response to a non-payment of royalties suit filed by Hilton against the footwear designers, with whom she launched a line in 2007, which asked for $1 million in unpaid royalties.

Hilton originally claimed Antebi failed to honour its licensing agreement and unlawfully squeezed out of paying her royalties. Her original licensing agreement with Antebi runs until the end of this year.
