New reports suggest Jennifer Aniston and Gerard Butler are definitely in a relationship, and a sexual one at that.

According to heat magazine, JenAn told friends whilst she was in Cabo for her 41st birthday, that she is having an “amazing” sexual relationship with her Bounty Hunter co-star, Gerard Butler.

A source told heat: "Jen invited only her closest friends, and she was the belle of the ball. How could she be anything but on top of the world.

"She says the sex is amazing. They have great chemistry across the board - sexually and intellectually."

They added: "In past relationships, she was always so stressed and focused on where it was going and how long they'll be together, and whether they were exclusive. But with Gerard she decided to enjoy it and not have any expectations."
