Lindsay Lohan is sleeping on the job hard at work on the set of The Canyons alongside porn star James Deen.

The two actors, filming a bedroom scene for the upcoming flick, seem to be diving into their roles. The Canyons, written by American Psycho author Bret Easton Ellis, is about the seedy underbelly of LA life. Sounds delish!

Lilo will play the role of Tara. As for her co-star Deen, he has appeared in over 4,000 porn films. We have a feeling the movie's sex scenes are going to be explosive.
