FRIENDS star JENNIFER ANISTON has refused to appear in her birthday suit in her new film THE GOOD GIRL.

Director MIGUEL ARTETA didn't realise that Jennifer has a no- nudity clause in her contracts - ensuring husband BRAD PITT is the only man who gets to see her curves.

A crew-member says, "A lot of people were making the assumption she wasn't happy stripping off because she is pregnant. But she said it was simply a matter of taste and she wasn't going that far. " (ES/WNWCAN/KMW)
