Friends with benefits?

Days after Vanity Fair released an interview with Robert Pattinson in which he declared he was just "friends" with Kristen Stewart, the two spent the night together at Hollywood's famed Chateau Marmont on Oct. 29, Usmagazine.com has learned.

The next morning, a source tells Us they shared breakfast together from Noah's Bagels (a plain bagel with walnut cream cheese for him; a blueberry with butter for her).

Around 8:30 a.m., they were taken directly to Hollywood's Deluxe Laboratories for a screening of New Moon.

"Rob wanted a cigarette so he went outside with Kristen for about 15 minutes," the source tells Us. "They were hugging, as Rob was smoking his cigarette and then he leaned down and kissed her on the lips. He had his arm around her almost the whole time."

What did they think of New Moon (out Nov. 20)?

They gave it two thumbs up.

"They were really happy with the way it turned out and gave great feedback," the source tells Us.
