Rob Pattinson & Kristen Stewart's Private Party for Two

Costars seen looking very coupled up at Avenue while other castmembers party at the Box in NYC

While most of the New Moon cast was at the official afterparty following last night's screening in New York, Robert Pattinson and Kristen Stewart slipped away for some private quality time.

Taylor Lautner, Ashley Greene, Kellan Lutz and Peter Facinelli all hit up the postscreening bash held at the Box. Ed Westwick also made a late appearance, with girlfriend Jessica Szohr arriving even later.

But Rob and Kristen were over at Avenue, holding court at a table upstairs with a bodyguard making sure people gave them their privacy—but no such luck.

Rob, trying to go incognito, wore a baseball cap, while Kristen was smoking a cigarette (which is illegal). Unlike the movie, there was no Taylor around, and Kristen seemed to only have eyes for Rob...

The costars were sitting right next to each other and kept whispering in each other's ears and laughing together. At one point, Kristen started stroking Rob's back.

And the two were still going strong at the club till 3 a.m.

In case there's anyone out there who still has doubts, looks like Robsten is totally on!
