The 20-year-old always swore she would never shoot a s-x scene, but Chris Silverstone - the director of her new movie I Know Who Killed Me - persuaded her to change her mind so she would get the critical recognition she craves.
Lindsay - who plays a stripper who is kidnapped and has both her legs amputated in the movie - told Nylon magazine: "Chris Siverston is a genius. We made a deal that I will do any film he wants me to do.
"At first I was like 'I can't do this, I'm getting my leg cut off. I don't want to look like that in scenes, I want to look decent!'
"But that was just me being young and stupid. And I have my first s-x scene in it, which I always said I wouldn't do. "I wanted to do this movie so people can see that I'm a f--king actress and I've been doing it forever and it's about time people see that. It felt so good to really get to act."
Lindsay first shot to fame as a child star in Disney film The Parent Trap.
So basically...this is like amputee p-rn...oh lilo, you never cease to amaze me.
