Twilight stars Kristen Stewart, 18, and Nikki Reed, 20, who are BFFs in real life, are going to play men in their next film together. “I’m doing a movie called ‘K-11’ in January with Kristen Stewart,” Reed told MTV.com. “It’s about a little-known section of the men’s county jail. I’m playing a [30-year-old] man, and Kristen’s playing a boy.” The movie takes place in the section of the Los Angeles county jail keeping gay inmates segregated from the general prison population. Stewart told moviesonline.ca: “It’s full of eccentric, crazy, off-the-wall characters, and me and Nikki play two of them. Jason Mewes wakes up in this place and doesn’t know where he is and tries to break out for two weeks. He tries to integrate himself into the community. It’s a really sweet but really screwed up little family in there.” Stewart’s mom, who’s a veteran script supervisor, is making her directing debut with the picture.
