New York, July 3 Kristen Stewart will reportedly do a steamy bedroom scene with Dakota Fanning in the upcoming Joan Jett biopic 'The Runaways.'

According to Life and Style, the 'Twilight' starlet will try her hand at some girl on girl action in the movie.

According to a source, the script calls for Stewart, who plays Jett in the film, to swap spit with Fanning, who stars as singer Cherie Curie, resulting in their clothes being "scattered all over their hotel room floor in one scene."

"Dakota's very controlled and poised. She's going to have to lose herself in this because it's pretty heavy," the New York Daily News quoted Stewart as saying. (ANI)
