Carl's Jr. is no stranger to risque commercials, and the company has done it again with this year's Super Bowl commercial.

The restaurant chain's ad (NSFW) features model Charlotte McKinney going "all-natural" in support of fast food's first "All-Natural Burger."

The ad will only air in Western states, according to Linsey Davis of Yahoo News, but it will surely rack up a lot of views online.
