Socialite Nicky Hilton

Socialite Nicky Hilton is being sued by a Chicago development group for breach of contract over a hotel renovation project in her name.

The 23-year-old is accused of not keeping her end of an April 2006 agreement to promote the redevelopment of 'Nicky O's Chicago,' a Nicky Hilton hotel.

Robert Falor Investments and Grand USA Hotel Supply also claim Hilton contracted out interior design work she was supposed to perform and tried to charge it back to the developer. Paul Fisher, Hilton's agent, is also named in the lawsuit.

Elliot Mintz, a media representative for Hilton, says, "Things are not always as they appear.

"When the facts surrounding this matter are known to the public I think you will find out that the person who has been most impacted by this action will be Nicky Hilton.

"In the meantime, I don't think anybody should draw any conclusions based on the simple filing of a lawsuit."
