Supermodel Heidi Klum can't sleep tight during these past days and maybe in the coming days too. It is all because she is facing a legal suit filed by a writer named Joel Lamontagne who claims that Klum's "Project Runway" reality show is based on a rejected script he penned two years ago.

In his court documents, Lamontagne claims he wrote a script for a reality show, called "America's Fashion Designer Search" and registered it with the Writer's Guild of America in 2003. Unfortunately for him that the company was too busy to proceed at that time.

In fact, when "Project Runway" began airing on Bravo in December 2004 with Heidi Klum serving as host, Lamontagne noticed numerous similarities between the show and his rejected concept. Thus, in his suit filed in Los Angeles, the writer also names all of the sponsors of the show, including The Gap and L'Oreal, and Elizabeth Hurley who will host the British version of the hit US cable show, and Walt Disney Pictures and Miramax Films, the companies behind the reality series.
