2K Sports is unhappy about an unauthorized release of a Top Spin 4 commercial that features Serena Williams and hot-as-(tennis)-balls gamer Rileah Vanderbilt sexing it up while playing the game. Apparently, Vanderbilt spilled the beans by posting the video on YouTube and tweeting about it.  2K Sports has this to say about the incident:  "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." Yeah, because sexy chicks, leather, and explosions do nothing but damage a video game's sales. Hurry up and peep the video before it disappears. [via Joystiq]
