Rob & Kristen promote New Moon separately to avoid hassle

Robert Pattinson and Kristen Stewart aren't undercover lovers — and to drive a stake through rumors that they are, the two are keeping a safe distance while promoting their "Twilight" sequel, "New Moon."

"They've requested to do press separately for the movie," says an insider about the film franchise's co-stars. "They really are good friends — and that's all — but they want to avoid being seen together. Any time they're photographed in the same place, the rumor mill just starts all over again, and that makes the paparazzi hound them even more.

"They requested to do things apart so the scrutiny around them will be a little less intense."
