"Don't believe the crap out there," says Nick Lachey about rumors of a Newlyweds breakup. "We're madly in love," adds Jessica Simpson. With the taping of a third season of their MTV show under way, the couple are branching out: Simpson recently inked a deal for a clothing label and is filming The Dukes of Hazzard. Lachey, who has appeared on The WB's Charmed, got his own MTV show. Busy as they are, no babies are on the horizon. "Daisy the dog is it for now," says Simpson.
