Kristen Stewart is "annoyed" people don't see her strip in her new movie.

The 20-year-old actress portrays a strip club worker in her latest film 'Welcome to the Rileys' but was disappointed that much of her preparation for the role went to waste.

She explained: "You don't actually see me strip which I suppose is a good thing as I was initially nervous about that. Now it's kind of annoying because I learned how to do it but you don't see any of it. But it's probably for the best."

Kristen - who is dating her 'Twilight Saga' co-star Robert Pattinson - recently revealed she was offered a job in a strip club when researching her role.

She said: "Well, I mean, like, doing this movie ... one shocking thing was to find how easy it is to flaunt your sexuality.

"Like, I went to a strip club with the director and the costume designer and it being an odd grouping of people going into a strip club in the middle of the afternoon, I was straight-up offered a job."
