Hostesses who work at one of the few venues the Eclipse cast hang out unmolested by fans and paparazzi say that “everyone knows” the Twilight saga co-stars are dating. One tells E!Online's Awful Truth blog that, “everyone here knows. They are the only cast members who will come in alone a lot.

"You can just tell by looking at them. They’re really cute together, always smiling.”

Another adds: “They just seem to make each other happy.”

An unconfirmed report claims Rob and Kristen's 'secret' romance will officially be out when the pair talk openly about their relationship in an upcoming magazine interview.
