Robert Pattinson and Kristen Stewart holed up at a hotel together during their brief stay in Los Angeles, it's claimed.

The pair reportedly spent the night together at the legendary Chateau Marmont on October 29, after wrapping shooting on Eclipse in Vancouver.

Rob and Kristen “shared breakfast together from Noah's Bagels (a plain bagel with walnut cream cheese for him; a blueberry with butter for her)” the following morning, according to Usmagazine.com.

Later they attended a screening of New Moon at Hollywood's Deluxe Laboratories.

"Rob wanted a cigarette so he went outside with Kristen for about 15 minutes," a source tells the gossip weekly.

"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."

Their verdict on the Twilight sequel?

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

Rob and Kristen - who are currently promoting NM in Japan and Mexico respectively - recently dismissed peristant rumours they are a real life couple, with the latter calling the romance gossip "retarded."
