Blake Lively and Penn Badgley were off-screen lovers while playing a couple on 'Gossip Girl.'

An alleged sighting of exes Blake Lively and Penn Badgley at Coachella last weekend has sparked speculation that the former couple may be back together.

ETOnline.com reported that the "Gossip Girl" stars were seen holding hands in the VIP Rose Garden on Saturday, but a rep for the actors, who share the same publicist, has called the report "wrong."

"She is shooting a film on the East Coast," the rep told the Daily News, adding that Badgley was at the music festival with "friends."

Lively, 23, has been working on the movie "Hick," also starring Alec Baldwin and Chloe Moretz, in Wilmington, N.C.

The actress and Badgley, 24, called it quits last fall after three years together.

But the stars, who first met several years before they started acting together on "Gossip Girl" in 2007, have remained close.

They finished filming the show's fourth season together last month, and Lively surprised Badgley with a birthday cake on set last November, shortly after their split.

"Penn was so surprised by her nice gesture," a source told The News at the time. "They seem to really be making their friendship work."
