Heidi Klum is at the centre of a new lawsuit filed by a man claiming he created the supermodel's PROJECT RUNWAY reality show.

Writer JOEL 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.

In legal papers, obtained by entertainment news website TMZ.com, Lemontagne also names 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.

The writer has also named all of the sponsors of the show, including The Gap and L'Oreal, in his suit, filed in Los Angeles.

Project Runway pits budding fashion designers against each other. The show debuted last year (04).

Klum will return as hostess of the second season of Project Runway, which premieres in the US on 6 December (05).
