Playboy magazine's 2010 playmate of the year Hope Dworaczyk showed up at the Rain Nightclub in Las Vegas on Saturday in a tiny pink dress that barely covered her up. There was a lot of leg and cleavage going on that night...

The model was really surprised that she landed the accolade, according to Radar Online.

Playboy boss Hugh Hefner presented Dworaczyk to the anxious crowd at the Palms Casino Resort. Also in attendance were Holly Madison, Jayde Nicole and Crystal Harris. George Maloof and Robin Thicke were the night's entertainers.
