Kristen Takes Part in Raunchy Sex Scene with TWO Men in New Film. Awks.

Kristen's new movie could make for awkward viewing on Robert Pattinson's part as his ex-girlfriend takes part in a raunchy sex scene.

Kristen Stewart, 22, will unveil her new film, 'On The Road', next week in which a raunchy sex scene features her topless as she gets steamy with two men.

The film will make for uncomfortable viewing for Rob Pattinson, who is still trying to come to terms with her betrayal after an affair with married 'Snow White and the Huntsman' director, Rupert Sanders.

Twilight star Pattinson was planning on attending the premiere screening in London to support Kristen, we're guessing this event has been knocked off his calendar.

“Can you imagine how cringe-worthy that would be for him?” an insider asked the Irish Daily Star.

“He's heartbroken, so not prepared to have all eyes on him while she gets it on with a couple of guys on screen.”

This news comes as it has been revealed that Kristen has been banned from attending Rob's upcoming movie premiere. Security staff have been told to keep the actress away from the red carpet for the launch of 'Cosmopolis' in New York this August.

Kristen's 'On The Road' tells the story of a couple of young American best friends, Dean (Garrett Hedlund) and Sal (Sam Riley), in the 1960s. They are the portrait of the 'Beat Generation'. Their search for happiness results in a fast-paced, energetic roller coaster ride with highs and lows throughout the USA. Lows include, you guessed it, the temptation of a certain girl called MaryLou (Kristen Stewart).

'On The Road' has been confirmed for release in the UK and Ireland in September.
