Disruptions on the movie set of the romantic comedy Four Christmases between co-stars Reese Witherspoon and Vince Vaughn of Wedding Crashers fame are reported to be getting worse.

First, Reese, the Academy Award-winning/anal-retentive Hollywood princess, can’t seem to handle Vince’s alcohol-laced, ‘fresh-from-the-club-last-night’ scruffy demeanor as he slogs onto the set in the morning.

She, on the other hand, is camera-ready from the crack of dawn.

She’s a one-take perfectionist; he’s an actor who likes to experiment and play around on camera. A source told the New York Daily News, “Sometimes Vince will be standing behind her and he has this look on his face that he just wants to kill her!”

Now, Reese is making an issue out of a scripted sex scene where she is supposed to appear nude in bed with Vince.

A spy on the set reports, “Reese has an issue with the scripted love scene. It is meant to be a funny, American Pie-style romp, full of bumps and laughs, but Reese is such a prude, she thinks it’s just too much.”

Vince ought to take this girl out drinking and partying with him during one of his all-night escapades. Get her to let her hair down, dance on tables, hang her head over the toilet. Who knows? Some fiery off-screen action just might make Four Christmases a much more enjoyable flick to catch in theaters next December.
