Boobs and Butts Front and Center in 'Unauthorized' Top Spin 4 Ad

This one may not be up for long. A new ad for 2K Sports' game Top Spin 4 features Serena Williams - billed as the world's sexiest tennis player - and Rileah Vanderbilt - billed as the world's sexiest tennis gamer served up as a delicious meal of lingerie-clad slow motion boobs, in-your-face butt and orgasmic moans.

Though the ad did emanate from 2K Sports, the brand is distancing itself from the work telling Joystiq, "As part of the process for creating marketing campaigns to support our titles, we pursue a variety of creative avenues. This video is not part of the title's final marketing campaign and its distribution was unauthorized."

Vanderbilt tweeted about the ad which has since been pulled from the brand's YouTube account but is currently viewable here or below.

What's 2K Sports up in arms about? We have no idea. This ad is no more nor less racy and salacious than many others out there. And it's not like tennis is the reserved country club sport it once was. Not with the likes of Anna Kournikova, Alana Bondarenko, Maria Sharapova, Jelena Dokic, the impossibly endowed Simona Halep and many more.
