Rumor has it that Twilight co-stars and former lovers Kristen Stewart and Robert Pattinson are back together, once again. Fans of the duo, also known as "Robsten," are anxious about whether the rumor holds any water at all.

Unfortunately the two on-again off-again lovers have not confirmed nor denied any of the rumors, but reports from eye witnesses continue to spot them together. Some speculate that the pair is secretly dating; trying to hide it from the public scope.

Pattinson appeared on Jimmy Kimmel Live, and mentioned that he was "homeless" at the moment, not having a permanent place because of his hectic schedule. According to HollywoodLife.com, "Rob doesn't have his own place in LA. When he's in town, he sometimes stays at the Chateau Marmont and very often at Kristen's when she's out of town. This gives him the chance to hang out with Bear and Bernie (the two rescue dogs they adopted together)."

Pattinson, at least admits that he never lost contact with his past girlfriend Stewart. He and Stewart had always been friends according to his recent Hollywood Reporter profile.

Some may be inclined to believe that since Pattinson does not deny the rumors, it serves as more reason for them to be true.

Fans of "Robsten" and of Twilight hope to see Edward and Bella reunited off-screen. The two had ended their relationship last Fall, but it is surely possible that they are secretly dating again.
