Kristen Stewart was banned from "groping" Dakota Fanning during their on-screen kiss for the new movie "The Runaways," because her co-star was just 15 when they shot the steamy scene.
The pair puckered up for a same-sex smooch during the film, which tells the story of the 1970s rock group fronted by Joan Jett, played by Stewart, and Cherie Currie, played by Fanning.

And Stewart, 19, admits she was restricted by working practice regulations when they filmed the kiss, because Fanning was so young.
She tells Access Hollywood, "She was 15, and I wasn't allowed to grope her. I'm actually not kidding, there are major restrictions that I don't remember (from) when I was younger."
She then stopped herself from spoiling the plot, adding: "I don't want to give anything way. It's a really passionate, hardcore scene ... It's just something that happened in their lives."
"The Runaways" hits theaters April 9.
