Reese Witherspoon is refusing to film a sex scene with Vince Vaughn and the pair have reportedly been clashing constantly on the set of the romantic comedy 'Four Christmases'.
An on-set source told the New York Post newspaper, "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".
In spite of being an Oscar winner and the more highly paid Hollywood star, Reese is unlikely to win the argument as Vince is one of the film's producers and he also oversaw much of the script writing.
It has previously been reported that Reese was unhappy with Vince's behavior on set because while she is keen to work hard and film on schedule, he allegedly turns up to work hung over, forgets his lines and is constantly fooling about on the set.
