Cameron Diaz and Ashton Kutcher will star together in the romantic comedy What Happens in Vegas for 20th Century Fox, according to Variety. Director Julian Farino (Entourage) is looking to helm from a script by Dana Fox.

Penn Station's Dean Georgaris and Mosaic Media's Michael Aguilar are producing the comedy, which teams Diaz and Kutcher for the first time.

Set in Sin City, the story revolves around two people who discover they've gotten married following a night of debauchery, with one of them winning a huge jackpot after playing the other's quarter. The unhappy pair try to undermine each other and get their hands on the money -- falling in love along the way.
