After School's Nana has clinched her very first solo CF deal for Korea's biggest diet brand!

Following after former models the Brown Eyed Girls and G.NA, new behind-the-scenes cuts of Nana showing off her Barbie girl figure for the camera prove that Nana is the perfect model to inspire people to shed the pounds they've gained over the colder months and get fit for the summer. In both versions, she's wearing skin tight one pieces that show off her slender and long figure.

Although busy with After School's "Flashback" comeback, Nana braved the 15 hour long photoshoot with ease.

A representative of the set commented, "As a former super model, she's already known as the role model for dieting amongst her fans. She will be showing off an even more healthy and beautiful body through the diet program."
