Us Weekly broke the story of Kristen Stewart's affair with Rupert Sanders last week, so it stands to reason that the tabloid is positioning itself as an authority on all things Robsten scandal.

So what's the latest on cheatin' ho K-Stew and sad, emo Pattsy? Seems Rob has chosen an unlikely place to mend his broken sparkle heart – the home of former co-star Reese Witherspoon.

Granted, Reese is married and it's unknown if she's currently at the ranch herself, but still, Kristen can't enjoy hearing that her man has already found a new sharp-chinned gazillionaire to shack up with.

According to a source, Kristen is "dying to save the relationship. It’s the only thing she cares about.” Rob, meanwhile, is said to be “a total mess . . . He’s questioning everything.” Doesn't sound good for the future of Robsten.
