Cameron Diaz is a Vixen in Vegas

Cameron Diaz and Ashton Kutcher arrive at the Los Angeles premiere of What Happens In Vegas held at Mann Village Theatre on Thursday.

Cameron, 35, plays Joy McNally who gets dumped by her boyfriend while Ashton, 30, plays Jack Fuller who gets fired from his job. Convinced by their friends, the two end up going to Las Vegas and in one drunken night of passion, they discover they’ve gotten married following a night of debauchery in Sin City, and while trying to end the marriage, 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.
