Robert Pattinson and Kristen Stewart did nothing to dispel rumors their relationship is a PR stunt at the New York premiere of Rob’s new movie Remember Me Monday night — after the pair showed up to the red carpet event in separate cars.

Real couples usually travel together!

Rob, 23, was busy working the crowds with his costar Emilie de Ravin when Kristen, 19, arrived and posed for pictures.

Stewart also signed autographs before entering the Paris Theater.

“She looked really happy,” a source said. “But she and Rob hardly spent any time together.”

It was recently claimed that Twilight star Kristen went “mad” when she was asked at a London fashion bash last week if she was dating Robert.

She reportedly stormed off, telling the roving reporter, “That’s none of your business.”

“Kristen went mad,” a source said. “She was very, very rude.”
