Twilight actress Kristen Stewart has already earned enough of bad name for herself, after she admitted cheating on her boyfriend of three years Robert Pattinson. And she is set to heap more embarrassment on Pattinson by indulging in sex scenes in her new movie.

Pattinson, 26, split from the Snow White actress, left, after she cheated on him with married British director Rupert Sanders. The controversial scenes in On the Road, based on Jack Kerouac’s infamous beat novel, should prove awkward viewing for heartbroken RPatz.

“He is keeping a low profile before On the Road is screened in London on August 16. He’s bracing himself because there’s a scene where Kristen gets involved with two men,” says a source. Perhaps Kristen, 22, who appears topless in the movie, isn’t Snow White after all.  .  

Stewart, 22, stars as the seductive Marylou, who is the 16-year-old wife of Dean Moriarty, played by Garrett Hedlund.

The new UK trailer of the film shows Stewart letting loose and dirty dancing with Hedlund, 27. The Twilight actress tackles several sex scenes in the film and goes topless.

The film has an official release date in the UK of October 12, 2012, but an official US date has not yet been revealed. Well, our sympathies with Rob!
