Jen Aniston and Gerard Butler film new scenes for their upcoming movie The Bounty Hunter on Wednesday in Yonkers, New York. The on-screen lovers have been getting particularly cozy together even when the cameras aren't rolling, as RadarOnline.com first reported.
Although there was no hand holding or kissing on set on Wednesday there were definite sparks between the co-stars.
"Gerard and Jen weren't touching or anything, but there's certainly chemistry," an eyewitness tells RadarOnline.com
"There was lots of flirting and giggling going on and they seemed to be with each other all the time, even when they weren't shooting scenes together.
"And who can blame Gerard? Jen is looking amazing and her body is absolutely smoking!"
