Cameron Diaz and Ashton Kutcher are in negotiations to team for the 20th Century Fox romantic comedy "What Happens in Vegas..."

The story is set in motion following a night of debauchery in Vegas, when two strangers (Diaz and Kutcher) discover they have gotten married and one of them has won a huge jackpot using the other's quarter.

In trying to determine the rightful beneficiary of the winnings, the pair attempt to undermine the other in order to get the money, and fall in love along the way.

Dana Fox wrote the screenplay whilst Julian Farino (TV's "Entourage," "The Office") will direct.
