Robert Pattinson and Tom Sturridge were together in LA yesterday for a walk. They brought along Rob's dog, Bear, who seemed to be leading the way. Tom headed west to LA after a stint in Chicago with girlfriend Sienna Miller. Sienna was in Illinois, so she could prepare for her upcoming film, Just Like a Woman, though she's moved to the desert in New Mexico to actually start filming her role as a belly dancer. Robert just wrapped up a stint on set, too. He was up in Canada for much of the last two months shooting Cosmopolis, and girlfriend Kristen Stewart was able to pay him a recent visit. Last week he attended the Cosmopolis wrap party to say bye to colleagues. Kristen's been in Hollywood lately, as well, focusing on her film work. She's prepping for a return to the big screen in Snow White and the Huntsman with yoga and horseback-riding lessons. Kristen and Tom will have lots of time together in the future, when they finally hit the press trail on behalf of their forthcoming movie On the Road from director Walter Salles.
