Porn Star James Deen to Lindsay Lohan -- No Hard Feelings

The porn star who was cussed out by Lindsay Lohan on the set of "The Canyons" tells TMZ ... he ain't mad at the actress for ripping him on set ... in fact, he's still a huge LiLo fan.

TMZ spoke with James Deen -- the porn star turned mainstream actor -- who says the audio of Lindsay telling him to "do your f**king job" made him smile ... because he had a great time on the project.

So why was Lindsay so pissed off that day? Deen says he and Lohan had a misunderstanding just a short time before the film shoot ... which put her in a bad mood.

“Hours before the rant she asked why I was doing this movie and I said 'For fun.' I meant for personal experience and enjoyment of working on a Bret Easton Ellis movie. I don’t think she understood my intention behind saying 'for fun' and thought it meant that I wasn’t going to try."

Deen thinks Lohan took his explanation as a shot at her craft -- which was definitely not his intention.
