NEW PHOTOS: Robert Pattinson Celebrates His Birthday Before Heading To Cannes

Robert Pattinson stepped out on his 23rd birthday after a long 12 hours of filming inside the studio. Pattinson arrived at the Global Grill and Satay bar and was shortly followed by Kristen Stewart, Ashley Greene and Jamie Bower amongst other cast members. They arrived around 9pm and left around 1am with Rob covering his face in the taxi as it sped off to his hotel for the evening.

Rob is expected to spend some time helping to shop a new film called Remember Me, directed by Allen Coulter and produced by Nick Osborne and Trevor Engelson.

The film will be presented to a number of buyers at the festival, along with three other titles from Summit Entertainment, which produced Twilight.

Shooting will begin this summer in New York. Pattinson will take a break from the shooting New Moon and Eclipse to make the picture. New Moon wraps shooting in May while Eclipse begins in August.
