Porn star Deen appears alongside the Mean Girls actress in the new movie, written by American Psycho author Bret Easton Ellis, but the project has been marred by rumours of on-set drama.
Deen has now revealed Lohan made an unusual request of the crew when the time came to film her racy sex scene, but they all threatened to quit when she asked them to strip to their underwear.
Deen tells Thedailybeast.com, ""She needed people to home in on the fact that this is a big deal to her - showing her boobs and doing a sex scene... No one cared - she tried to make it a bigger deal - no one cared - so then... she said, 'When Julia Roberts does topless scenes, she makes the whole crew shoot in their boxers! I want that!' And the whole crew just rolled their eyes and was like, 'We're not doing that. We'll do that for f**king Julia Roberts, but not you. Go find another crew; we'll just leave'.""
However, director Paul Schrader was determined to keep his leading lady happy, so he oversaw the scene wearing nothing but his socks.
Deen adds, ""Schrader looked her dead in the eyes and said, 'I'm not making my f**king crew do that, but you know what?' And then he stripped off all his clothes except for his socks, strutted across the room to the monitor, stood there, and just said, 'Action!' And the cameras immediately started rolling, Lindsay jumped in the bed, and we nailed it in one 15-minute take.""
