What Happens in Vegas is to hit the wide screens on May 9. Ashton Kutcher and Cameron Diaz's drunk scene video above was leaked on the Youtube, apparently, most of movie lovers believe it as a viral marketing way to promote the film. What Happens in Vegas tells two strangers (Cameron Diaz and Aston Kutcher) awaken together to discover they've gotten married following a night of debauchery in Sin City, and one of them has won a huge jackpot after playing the other's quarter. The newlyweds devise ever-escalating schemes to undermine each other and get their hands on the money -- only to find themselves falling in love amid the mutual backstabbing.
