Jennifer Lopez & Heidi Klum: No Project Runway Feud

Jennifer Lopez's rep has denied claims that Heidi Klum is furious after the pop diva pulled out of an appearance on the supermodel's show, Project Runway.

The singer dropped out of judging the catwalk contest at the eleventh hour after allegedly suffering an ankle injury.

And, according to reports, Jen's last-minute cancellation received a frosty responce from Heidi.

MSNBC quotes a source as saying, "Heidi went from one big-name judge for the finale to none. It was embarrassing, especially the excuse that (Lopez) was hurt.

"She can forget about Heidi and (husband) Seal attending Marc Anthony's birthday party in New York after this."

But, speaking to Entertainmentwise, Jen's rep has rubbished the claims as “not true.”
