Kristen Stewart Pool Shoot Photos With Robert Pattinson's Friend Emerge

Kristen Stewart has appeared in a pool shoot for the September issue of Marie Claire magazine.

The shoot took place prior to her affair with director Rupert Sanders becoming public last month, and the "On the Road" actress stars in the photos along with her co-stars.

The shoot allegedly took place on the rooftop of France's Five Hotel in the pool. Stewart can be see posing with "On The Road" co-stars Garrett Hedlund and Sam Riley.

Meanwhile Stewart has reportedly pulled out of the London premiere of her new movie "On The Road" as she is reportedly too embarrassed to make public appearances following the recent cheating scandal.

Stewart, 22, cheated on long term boyfriend Rob Pattinson with married father Rupert Sanders, who directed her film "Snow White and the Huntsman." The actress apparently fears that making an appearance on Aug. 16 would only distract from the film, which is an adaptation of Jack Kerouac's classic novel.

"Kristen won't be doing the red carpet for 'On The Road,' she's too ashamed to show her face in public right now," a source told Radar Online.

"After everything that has been said, and in light of the revelations that she cheated on Robert with director Rupert Sanders, she's running scared at the moment."

Tom Sturridge, Stewart's "On The Road" co-star, is good friends with Pattinson, which has scared the actress off even more from attending the premiere.

"There's also the dilemma of standing next to her co-star in the movie, Tom Sturridge. He's very close to Rob and Kristen thinks it would be awkward for her to promote the movie on the red carpet alongside him," the insider explained.

"Kristen is very proud of her work for 'On The Road,' she grew up reading Kerouac novels and this is a production she always wanted to star in. If she appears at the London premiere, it will detract people from the movie itself and Kristen doesn't want that at all," the source added.
