Being photographed nude is nothing new to supermodel Miranda Kerr, so it's no surprise that when her top fell down and exposed her bare breasts during a recent shoot for her Kora Organics skincare line she just shrugged it off and kept on working.

The sexy 30-year-old was in Miami last week for the photo shoot when a gust of wind took down her top -- something she didn't notice until an assistant rushed in to help cover her back up. Miranda laughed it off with a surprised look on her face (see pics here).

Last month Miranda revealed that she wasn't renewing her contract with Victoria's Secret because she has too many other projects.

"This is a natural evolution," she told the Sydney Morning Herald. "The thing is, I've been modeling since I was 13. I'm now entering a new phase in my life. I have felt this coming since my son was born and, after I became a mother, I realized I needed to prioritize my time."

Miranda, who is very active on Twitter and Instagram, didn't mention her wardrobe malfunction, but she did post a photo of herself on a beach from a new Vogue Italia shoot. She appears to be topless in the image -- something she's done before for Vogue Italia as she showed a bare breast in the magazine's 2010 3D issue.
