Lindsay Lohan promises to reveal "a lot more" playing a stripper in her new movie.

The 20-year-old star will portray a pole-dancing stripper who is kidnapped, tortured and has her legs cut off in 'I Know Who Killed Me'.

Lindsay told US chat show host David Letterman: "You'll be seeing a lot more of me in this movie. It's a really dark, scary film."

The 'Mean Girls' star also claimed that while she parties hard, she works hard too and wants to become an Oscar winning actress.

She said: "I want to get a nomination. I want to win an Oscar. I want to be known for more than, like, going out.

"I bust my ass when I'm filming and when I have time off, yeah, I like to go out and dance."

'I Know Who Killed Me' is released on July 27.
