Arriving at NYC lounge Avenue at 1:30 a.m. on Nov. 20, New Moon co-stars Robert Pattinson, 23, and Kristen Stewart, 19, made an adorable couple. "They were escorted to a corner table on the mezzanine," says a club insider. "They were chatting and laughing until 3 a.m. They came and left together -- just them. It seemed like a date for sure."

But under the spotlight, the Twilight couple still won't admit they're together, despite holding hands in Paris on Nov. 10. They didn't let themselves be photographed together at the New Moon world premiere in LA on Nov. 16. And at a Nov. 19 screening in NYC hosted by D&G and the Cinema Society, "Kristen and Rob both seemed in good spirits -- but they didn't walk together," says an eyewitness.

And when it comes to interviews and talk-show appearances, they've come up with increasingly clever ways not to answer the question everyone's asking: Aren't you guys dating?
