The busty blonde is teasing her best assets in the commercial, walking around a farmers market au naturel while promoting the fast food chain’s all-natural burger.
She barely keeps covered with the help of fruits and vegetables.
While she’s happy to tease her fans, the Guess model won’t be baring it all any time soon.
She told FOX411, “I believe there’s a time and a place for [posing nude]. I don’t think I’m ready for it. I’ve been asked to pose for Playboy and there’s this magazine Treats, it’s nude. I’m away from it for now, unless along the line of Vogue or something amazing, but for now, no.”
Like Upton, McKinney could land in Sports Illustrated’s Swimsuit Issue someday… just look at this Instagram pic!
Charlotte added that she admires Kate. "Personally, I don’t compare myself at all to her. I think we’re two totally different people but I admire her business aspect of her career, I think she’s done an amazing job."
