Charlotte McKinney Goes Au Naturel For Carl’s Jr.

Carl’s Jr. has done it again. Known for their sexy ads featuring pop culture’s hottest ladies – you know who we’re talking about – Paris Hilton, Audrina Patridge, Kate Upton, Nina Agdal, Ashley Hartman, Kim Kardashian, Emily Ratajkowski and Sara Underwood – they’ve since upped the ante.

Like they say, if it ain’t broke, don’t fix it.

So, they chose buxom Guess model Charlotte McKinney to introduce the brand’s first fast food All-Natural Burger with grass-fed, free-range beef. And she is, like the burger itself, all-natural (and not wearing any clothes). Though you could care less about the burger, it is making us hungry. Check out her deliciously hot commercial where she poses nude below:
