Rirsten? Robsten? Krob? These don't have quite the ring of Brangelina and Bennifer. Nonetheless, they've got to be the most talked, blogged, gossiped, and written about pair since the first paparazzo pulled on a nondescript hat and slung a camera over his shoulder.

You know where you have seen them: in those mildly creepy, sugary Twilight movies based on the book series written by a Mormon. K-Pat's relationship is said to have begun sometime during or after the second Twilight film. While Pattinson and Stewart remained as stealth as possible about their life together, all hell broke loose when Stewart was recently caught having an affair with director Rupert Sanders. Could the whole Twilight franchise come crashing down? We doubt it.
