Kristen Stewart Shows Up At Robert Pattinson's 'Remember Me' Premiere (PHOTOS)

'Twilight' lovers Kristen Stewart and Robert Pattinson haven't admitted they are an item, but Kristen made an appearance at the premiere of Robert's new movie, 'Remember Me,' Monday night in New York.

Sunday night the pair enjoyed a PDA-filled dinner with a group of friends at Tribeca's Laconda Verde Italian restaurant.

"Robert and Kristen sat really close together and kept touching and rubbing each other's arms as if no one else was around," says a fellow diner told the Daily News. "They definitely appeared to be an item."

Below are pics of Kristen and Robert, with his costar Emilie de Ravin, at the premiere. They did not pose together.
