A "sexy" commercial for 2K Sports' Top Spin 4 has been leaked onto the internet.

The video features "the world's sexiest tennis player," Serena Williams, and the "world's sexiest tennis gamer" firmly gripping PlayStation Move controllers and grunting their way through a match in Top Spin 4.

"As part of the process for creating marketing campaigns to support our titles, we pursue a variety of creative avenues," 2K Sports said in a statement. "This video is not part of the title's final marketing campaign and its distribution was unauthorized."

Top Spin 4 is out now.
