Paris Hilton is being sued by a footwear company for $2 million.

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 a rival product.

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

Antebi's countersuit says it is seeking the return of $2 million already paid as royalties, and claims she breached her contract after inking a deal with rival company Retouch and promoting the resulting Parisian Parc footwear line on social media.

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.''

Paris originally claimed Antebi failed to honour its licensing agreement and unlawfully squeezed out of paying her royalties.

Promoting her line with Retouch in September last year, the former reality TV star tweeted: ''Obsessed with all my new shoe designs. Love how all the fabrics & colors go perfectly with my [handbags].''

Paris' original licensing agreement with Antebi runs until the end of this year.The case continues.
