Robert Pattinson was decked out in his beloved Orioles hat as he arrived back at the Toronto airport and headed out of Canada earlier today following a quick visit to the city. Rob Pattinson arrived in Toronto just one day earlier to do some postproduction work on Cosmopolis with director David Cronenberg. While Robert is tying up loose ends on this project, his girlfriend Kristen Stewart is working on Snow White and the Huntsman battle scenes overseas in the UK. Robert has visited Kristen in London during some of his downtime, which has meant double dates with his best friend Tom Sturridge and Sienna Miller. Robert and Kristen will be reunited soon to start promoting Breaking Dawn Part 1 ahead of its November release. The third part of their onscreen love triangle, Taylor Lautner, already revealed to us that the first part of the Twilight finale made him cry.
