Kristen Stewart gets into shape to look like 'porn star'

Kristen Stewart has revealed that she’s going to look like a porn star in Nick Cassavetes’ film Cali.

Stewart, who rose to fame playing Bella Cullen in The Twilight Saga series, is to hit the gym after vowing to get into 'the best shape of my life' for her next role.

“I’m going to get into the best shape of my life. I’m going to look like a stripper. I’m going to look like a porn star,” the Daily Telegraph quoted her as telling Women’s Wear Daily.

Stewart will play Mya, who flees Los Angeles with her boyfriend after selling a snuff film, but returns years later to save her sister when she lands in trouble.

The 22-year-old admits she was intrigued by the 'extreme in every way' script and hopes she can get to grips with her character’s psyche.

“A lot of times, you’ll read a script and you can identify with things that are very surprising, things that kind of shock you about yourself."

“And the process of making the movie is finding out why those feelings occurred.

“Sometimes they’re not always easy to define … (But) if you don’t know why someone is the way that they are, then you’re just playing a caricature of a girl,” she said.
