Hot on the heels of mopey KRISTEN STEWART cheating scandal, her so-called boy “fiend” and co-star, even mopier, ROBERT PATTINSON  has moved out of the house they once shared.

Sources say Rob, 26, is  “heartbroken and angry” and “devastated” and reportedly –has  packed his bags. He may be leaving on a jet plane – don’t know when he’ll be back again.

"I'm not sure they'll be able to recover from this," a source said of Stewart and Pattinson, a  “couple” of three years, who first met making the sparkly vampire movies aimed at gullible pre-teens. 

The Hollywood Reporter says Stewarts confessional about boinking her much older “Snow White” director Rupert Sanders, 41, won’t affect box office gross for the last of the Twilight flicks.

Yet the Twitter sphere was suddenly now agog with queries like “WHO would cheat on *swoon* Edward Cullen?”
