'Twilight' Co-Stars Speak Up on Robert Pattinson and Kristen Stewart's Romance Rumors

Despite Robert Pattinson and Kristen Stewart's repeated denials concerning rumors of them dating, speculation keeps escalating that they embark on an off-screen love relationship. Putting the brake on the false persistent dating rumors which seemingly won't come to an end, "Twilight" co-star Edi Gathegi told E! News' Marc Malkin during his recent stop in Los Angeles for the launch of Catherine Hardwicke's "Twilight: Director's Notebook", "I can't even think of those two together at all. Kristen has a boyfriend! It's on-screen and that's it."

In line with Edi, fellow "Twilight" star Ashley Greene said that she thinks Robert and Kristen "are, in a way, victims of their own success." During her appearance at the "Twilight" at Midnight DVD launch event at Hollywood's Hot Topic store recently, Ashley explained, "Their chemistry is fantastic, but no, they are not in a romantic relationship. They are good actors [is] basically what it comes down to."

"That's kind of the advantage that we had on Twilight. Everyone has such great chemistry. With as big a cast as it was, and as young a cast as it was, we all just got along so fantastically," Ashley went on adding.

Providing evidence to the close bond that "Twilight" cast have been developing, Ashley revealed Peter Facinelli, who plays Dr. Carlisle Cullen in the vampire drama flick, recently invited everyone for dinner. "He cooked pasta for all of us," she said. "We all came to his house and ate and drank and talked. It's a bizarre thing, because we kind of all looked at each other and were like, 'Sooo, what's your life been like?' It was fun."

Playing on-screen lovers in "Twilight", Robert Pattinson and Kristen Stewart have repeatedly been hit with dating rumors. Both of them have denied they are an item though. Besides, Kristen has had a boyfriend, actor Michael Angarano, whom she's been dating since 2006.
