Blonde bombshell Charlotte McKinney absolutely stunned during a hosting gig at the grand opening of Steve Wynn's newest casino on Wednesday night, Page Six reported. The busty Carl's Jr. babe showed off her curviest assets in a sexy black dress at the event for the Encore Players Club in Las Vegas.

The 22-year-old model wore a floor-length black dress and showed off some skin with a high slit, showing off her understated strappy black pumps. She showed off her cleavage with the gown's diamond cut-out neckline which was so low, it seemed as if she was dangerously close to having a major wardrobe malfunction. She finished her look with a pinky-nude lip, a natural but sultry smoky eye and styled her long blonde locks in loose waves.

McKinney, a former "Dancing With the Stars" contestant presided over the opening ceremonies, according to local paper the Las Vegas Sun. The new Encore Players Club casino is aimed at millennials, people who were born between 1980 and 2000, and is a space where guests can gamble, watch sports and party.

TV personality Nick Cannon and professional body builder Jay Cutler also attended the star-studded event, according to the Daily Mail.

A preview of the space over New Year's Eve weekend featured appearances by UFC ring girl Arianny Celeste, DJ Pauly D of MTV's "Jersey Shore," and Miami Marlins great Giancarlo Stanton, according to Las Vegas Eater.
