Sorry, Twihards: Robsten are unbroken.

Sources confirmed that Robert Pattinson and Kristen Stewart broke up, putting a stake through the hearts of vampire shippers everywhere.

PEOPLE reports that the couple of three years called it quits, but that all may not be lost for fans of the on-and-offscreen vamp lovers. Insiders say that the duo may not be completely dunzo, and that they wouldn't be surprised if they got back together.

R-Pattz and K-Stew have been famously cagey about their relationship, acknowledging it publicly and outright only when Stewart was caught making out (and maybe more) with her 'Snow White and the Huntsman' director Rupert Sanders.

The news is somewhat surprising, as just as recently as May 8 the pair hung out right after the Met Gala in New York City. However, rumors of a rift emerged again when Pattinson and Stewart spent his birthday apart.

On the bright side, poor Stewart will at least be scowling for a reason now.
