At the opening of the Project Runway finalists' show in Bryant Park during Fashion Week in NYC Friday morning, Heidi Klum announced that the much buzzed about appearance by Jennifer Lopez as a guest judge on the season finale will not be happening.

"Jennifer Lopez was going to be our guest judge, [but she] cancelled yesterday due to a foot injury," Heidi told the audience.

Despite Heidi's comments, Gunnar Petersen, Jennifer's trainer, denies any mishap, telling OK! "No injuries, all good."

The show must go on, however, even as it changes networks and guest judges.

"A great five years at Bravo comes to an end today, thank you so much, you did a beautiful job putting the show on the network," she added, as the show is moving to Lifetime.

So if Jennifer is out, who's stepping in?

None other than fashion guru Tim Gunn!

"I'm happy to fill in last minute and will be impartial and unbiased to the designers," said Tim.

Make it work!
