It was only a matter of time, really, before goofy Cameron Diaz and goofier Ashton Kutcher got together for a romantic comedy. The two are in talks to do What Happens in Vegas [1], and not unlike Lucky You [1], I have an inkling that this will be chock full of "roll the dice and take a chance in love" puns.

Variety has a plot description:

Set in Sin City, 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. Unhappy pair try to undermine each other and get their hands on the money -- falling in love along the way.

The article continues to say that neither actor has definitely signed a deal, so Variety may be bluffing on this one.
