Ashton Kutcher and Cameron Diaz cruised over to New York's Fire Island to continue filming "What Happens In Vegas" which if these pictures are any clue, it doesn't. Diaz and Kutcher filmed a romantic wedding proposal scene on the beach and just to make sure things didn't get to hot and heavy, Demi Moore was on set to keep an eye on her hubby Ashton. I was going to warn you with a spoiler alert but I think this movie is going to stink so I just saved you $10 ($15-$20 if you live in Hollywood). More pics after the jump!
