When Joy (Cameron Diaz) hits Vegas to get over her breakup, and Jack (Ashton Kutcher) heads to Sin City to forget about his family drama, the two strangers meet up for a wild night to remember…er, forget, in What Happens in Vegas. When they realize they got hitched Vegas style (oops!) and end up slot machine millionaires, an all-out battle of the sexes ensues. Even though they are complete opposites, a judge (Dennis Miller) sentences the couple to 6 months of "hard marriage," so this accidental knot has to stay tied! Well, they might not be able to stand each other, but they sure look pretty as a couple! Flip through our list of duos who shine on -- and off -- the red carpet!
