Twilight star Kristen Stewart is set to mix vamps for tramps in a saucy new film, in which she bares almost all. The teen star will play a young lap dancer and prostitute in James Gandolfini's gritty new film Welcome to The Rileys.

And, as the promiscuous Mallory, she even offers to service The Sopranos star.

Reports suggest Stewart walks around naked in many scenes and was so terrified of stripping on camera she insisted "Twilight" co-star and pal Nikki Reed join her on the set of the film in New Orleans, Louisiana.

In a recent interview with About.com, Reed said, "I'm going with Kristen to New Orleans... while she's shooting and I'm a good support system... I have to go to be with Kristen."

And now Stewart is talking about the project, telling WENN she thinks the film will be a hit - because "Twilight" fans will want to see what she looks like naked.

She explains, "It's an independent movie that nobody would normally see and now it's like, 'Oh, let's go see Bella ('Twilight' character) in this stripper movie; it'll be crazy!'"

And Stewart admits the shoot was a blast: "Working with James Gandolfini and (co-star) Melissa Leo, who is just incredible, was the most fruitful life-changing experience on a movie that I've ever had.

"It was just the hardest subject matter I've ever had to deal with - I play a very broken young girl who is a runaway. She's a street kid. She's working in a strip club and James Gandolfini's character is just as dead inside as she is - and they wake each other up."
