Don't worry, Nina, it's perfectly natural!
Sports Illustrated model Nina Agdal, AKA, Adam Levine's ex-girlfriend, was recently having a blast shooting the new Bebe campaign in Miami Beach when her slinky top exposed her right breast and nipple!
Nina didn't seem too bothered by it, however, and simply fixed it up and went right back to posing! Atta girl!
Nipples are nothing to be ashamed of!
