Look Away Kristen Stewart! Robert Pattinson Enjoys Steamy Romp With Co Star On Set Of Maps To The Stars

Robert Pattinson hasn't exactly looked very happy since his break up with Kristen Stewart, but he certainly had a smile back on his face earlier yesterday as he enjoyed a passionate romp with co-star Mia Wasikowska as they shot scenes for new movie Maps To The Stars.

Rob plays Mia's limo driver boyfriend in the David Cronenberg-directed drama and clearly the couple are well cast as lovers based on the chemistry sparking on set yesterday as they shot scenes and didn't seem bothered about having to get up close and personal with each other on camera.

The intimate scene has the couple stretched out on the floor while they passionately kiss, with Rob grabbing the actress' hair as well as her bum as he caresses her neck - pretty steamy stuff. While sex scenes are sometimes awkward affairs Rob seemed to be having a great time and could be seen laughing with Mia and the director in between takes.

The last time we saw Rob locking lips on the big screen was with then girlfriend Kristen Stewart in the final installment of the Twilight saga, Breaking Dawn Part 2 released last November. But with the end of their romance in May this year, after four years together, we doubt we're going to be seeing those two puckering up again, or are we?

Insiders have reportedly told Us Weekly a reunion between the pair could be on the cards. According to the mag, the couple discussed their relationship when the heart-throb visited Kristen's Los Feliz mansion on August 4.

It was "a very intense conversation," a source told the mag. "They will probably pick up where they left off."

While they might have broken up, the source claims neither one has really moved on.

"Rob is obsessed with her," the source went on, "She's still heartbroken. She can't seem to get over him."
