Gerard Butler and Jennifer Aniston …just friends?

If Gerard Butler (40) and Jennifer Aniston (41) still want to convince us that they’re nothing more than just good friends, then they really need to try a bit harder, E! Online reports.

While grabbing your leading lady’s bottom for the red carpet flashbulbs is one thing, doing it when you think no one’s looking is really quite another.

The pair were snapped posing for pictures aboard a yacht on the River Seine in Paris on Saturday, as they explored the French capital while on their promotional tour for their new release The Bounty Hunter.

As Jennifer warmly put her arm round her co-star’s waist as they were snapped with a lucky fan, Butler placed his hand on her bottom and clearly this wasn’t just a cheeky pat either, as Gerard appeared to really get a good handful of her pert derriere – little realising he was being snapped from behind at the same time.
