A racy, unreleased trailer with Serena Williams and actress Rileah Vanderbilt (who has appeared in such films as the slasher film Hatchet) that was shot for Top Spin 4 was briefly leaked on YouTube, then pulled, but not after getting over a million views.
Some still shots still exist, including the image below, which is definitely red-hot.
2K Sports released this statement before the video was removed: "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."
Serena Williams' reaction to the trailer? She tweeted that it was "awesomely sexy."
