It is the first time they have appeared in public together since the couple's infamous cheating scandal just a few months ago, and Yahoo! Movies has exclusive video of the moment (below).

Robert Pattinson and Kristen Stewart had their public reunion at the world premiere of "The Twilight Saga: Breaking Dawn - Part 2" on Monday night in Los Angeles. The two were cozy, even though they separated mere moments after stepping foot on the carpet to do press.

Still, we caught Stewart caressing Pattinson's back as they stood together in front of throngs of fans and media.

First, the couple arrived in separate SUVs that pulled up at the same time and, as Yahoo!'s Michael Yo observed, "Everybody knows who's getting out of them." They stepped out separately -- yet near -- then came together to pose for photos arm and arm while among studio executives.

Before they scooted further along the carpet in the midst of a crowd of people, Stewart was seen saying something quickly to Pattinson then cracking a quick smile. Posing for cameras again, arm and arm, Stewart brushed her hand against Pattinson's back, giving him an ever-so-slight-yet-loving squeeze. Then the couple parted to do more press, but not before giving each other a quick acknowledgment.

We spoke with body language expert Dr. Lillian Glass, who noted it was impressive that Stewart has become the "affectionate aggressor" in the relationship. On the black carpet, Pattinson and Stewart "look very relaxed around one another and she rubs his back which shows she is supportive of him and affectionate unlike she has been in the past," Glass said. "He has been the affectionate one in the past and now she has reversed her role. She knew that he was going to be interviewed first so the back rub was a good luck to him and a signal of support and affection."
