2K Sports just debuted a sexy new commercial for the recently released tennis game, Top Spin 4, in which tennis star Serena Williams ("world's sexiest tennis player") takes on Rileah Vanderbilt ("world's sexiest tennis gamer"). They go head to head playing Xbox's Kinect in the tennis game. And Serena is featured as one of the game's characters.



Pics of the new ad, which features Serena flaunting her ASSets in fishnets and a leather one-piece and may be too hot for tv, when you read on...

Serena, donning all-black tight fighting leotard, and Rileah wearing an even sexier black outfit herself, battle it out, all while flames decorate the background.
