2K Sports has pulled a controversial, provocative commercial for its video game "Top Spin 4." The advertisement featured Serena Williams, called the "the world's sexiest tennis player," and actress Rileah Vanderbilt, called "the world's sexiest tennis gamer," dressed in suggestive outfits and grunting. The video was never officially used as a marketing tool, and it was allegedly uploaded on the Internet by Vanderbilt.

"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," 2K Sports said in a statement.
