An advertisement for Top Spin 4 has made its way onto the internet, but it's not what one would call "official." Featuring Serena Williams, the ad was definitely made with 2K Sports' money and effort. We've attempted to get an official statement from 2K Sports, but the company doesn't appear to want to talk until it's eliminated every instance of the video from the internet.

The ad was originally posted on YouTube by the actress featured in the commercial -- apparently she wasn't satisfied with 2K Sports' decision to cancel the public release.

Update: 2K Sports' official statement: "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."
