From the article I referenced in my OP-
"For anyone who’s been wondering what Jennifer Aniston’s doing to get over her rejection from Brad Pitt, here’s the answer!
The world now knows what those on the New York set of The Bounty have suspected: she’s hooked up with Scottish hunk Gerard Butler.
Pictures taken on the set on 10 July have caught the couple arm in arm – after the cameras stopped rolling.
They even practise kissing scenes after the cameras have stopped rolling!"

While Renee Zellweger and Bradley Cooper are reportedly dating, and will be seen together in two movies later in the year, the article you refer to reports that they were seen together in Spain -
"The actors have been snapped with their arms around each other at the luxury Hotel Arts Barcelona. They were also spotted laughing and joking as they had breakfast before visiting a local church."

As it doesn't mention anything about their behaviour while filming on set I think I'll stick with Jennifer Aniston & Gerard Butler.

Hope this helps.
