Robert Pattinson was on the London set of Bel Ami this morning, dressed in his old-timey costume and strolling behind the scenes with a mug of tea. He's home in England again after a whirlwind week of promoting Remember Me in NYC, with many interviews surrounding his big Monday night premiere with Kristen Stewart. He left town on Tuesday evening, but we just got a behind-the-scenes peek at him and Kristen having fun with his family at the screening's afterparty. His film doesn't hit the big screen until next Friday, but for now Rob seems fully occupied working on his period piece with Uma Thurman.
