Jennifer Lopez will serve as a judge on the season 5 finale of Bravo's Project Runway.

The actress is shooting the show Friday, the source adds.

Nina Garcia wouldn't confirm the news, but hinted the finale "is going to be unbelievable."

"The guest star is one of the most iconic women around. It's going to take the cake." Judge Michael Kors tells the new issue of Elle she could be a fashion editor.

"She is curious about what's new and what's next, but at the same time she knows how to edit perfectly for her look and lifestyle."

J. Lo is obsessed with fashion. She is a great choice, but she's going to stink things up. Refer back to the pic above.
