Courteney Cox has vowed never to work with husband David Arquette because she fears the strain it would put on their marriage. The couple appeared on screen together in spoof horror movie Scream, but Cox insists she wouldn't ever juggle her family and professional life again. She says, "It's just asking for trouble. If you're living with someone, it's not a good idea to place the kind of strain on your marriage that comes from being on set together for 14 hours a day. "I think we hang out together enough. This way, at least one of us is home in the evening without being totally exhausted."
