Cameron, Ashton and Demi Team Up In Tokyo

Yesterday, the Japanese paparazzi got an eyeful of Ashton Kutcher and Cameron Diaz at the Imperial Hotel for the “What Happens in Vegas” press event. And today, the two co-stars were joined by Kutcher’s wife Demi Moore at the big premiere.

Tokyo’s Marunouchi My Plaza was the place to be earlier today (August 6), as a throng of Japanese fans converged to catch a glimpse of the American film stars.

The “Punk’d” stud looked hot in a black suit with a silk printed button-up shirt underneath, while his wife rocked a shimmery black and grey knee-length sleeveless dress.

And never one to disappoint, Miss Diaz sported a sexy sleeveless belted white minidress with a pair of matching heels and a pulled-back hairdo.

As previously reported by Gossip Girls, "What Happens In Vegas" is a story that "revolves around two people who discover they've gotten married following a night of debauchery."
