Carly Simon reportedly wrote her hit "You're So Vain" about Warren Beatty, who sets the gold standard for Hollywood playboys. His list of conquests reads like a Hollywood Who's Who; Natalie Wood, Diane Keaton, Goldie Hawn, Julie Christie, Cher and Madonna. Beatty, who once said, "Just because you need a quart of milk doesn't mean you have to go out and buy a whole cow," finally settled down with "Bugsy" costar Annette Bening in 1992. The pair has four children.
