Sexy Serena Williams Top Spin 4 ad leaks

Flames, grunts and slow motion bottoms – it is tennis star Serena Williams as we've never seen her before.

In a leaked video advertisement for tennis simulation Top Spin 4, Williams, described as "the world's sexiest tennis player", and an actress described as "the world's sexiest tennis gamer", pout and frolic as they play the game with the PlayStation Move controller – to the soundtrack of sexy grunts.

According to Joystiq, the ad was "definitely made with 2K Sports' money and effort". It was originally posted to YouTube by Rileah Vanderbilt, the actress who played "the world's sexiest tennis gamer", after 2K Sports axed the project.

The video is now set to private, although it exists elsewhere on YouTube.

In a statement, the publisher insisted the ad was not intended for official release. "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 unauthorised."

8/10 was the verdict in Eurogamer's Top Spin 4 review.
