Things got a bit messy for Robert Pattinson last night on the Toronto set of Cosmopolis, where he filmed a scene that involved getting pie-d! Robert's good-looking face was covered in cream after someone threw a dessert at him, but it was all part of the movie. He was even spotted laughing afterward while he used a towel to get remaining bits out of his ears. It was a long day of work for Robert, who was spotted between scenes in his favorite red jeans during the afternoon. While Rob's up in Canada working, his girlfriend Kristen Stewart was home in the States. Kristen Stewart did yoga during the morning while in LA and later stepped out solo to run errands.
