EXCLUSIVE PHOTOS - Robert Pattinson Shows Off His Beefier Bod On A Food Run

Rob Pattinson's buff bod may not stick around for long ... the extra pounds are for his upcoming role as a military interrogator in Mission Blacklist ... or is it breakup weight? Seeing as Rob's rumored to be dating Sean Penn's daughter Dylan and getting his flirt on with various ladies on the Hollywood club scene, we have to believe he's putting on pounds for his new film.

Rob gave us a peek at his beefier arms and torso while grabbing a to-go bag of food in Los Angeles on Wednesday, and he also showed off a serious amount of scruff. So much for our clean-cut Edward Cullen fantasies!

And speaking of film roles, when the news broke this week that Charlie Hunnam had dropped the role of Christian Grey in the Fifty Shades of Grey film, Rob's name was thrown into the mix. But don't worry, it's not what you think!

"[Charlie] dropped out of the project because he didn't want to be typecast," a source tells People magazine. "He didn't want the Robert Pattinson-esque attention that would come along with taking on this role." Ouch! But Rob's bank account is probably ten times bigger than Charlie's, which isn't really the worst thing either...
