Miranda Kerr bares her breasts in topless Instagram photo

Miranda Kerr isn't afraid to show some -- or all -- of her skin. The model went nude for a photo shoot with photographer friend Chris Colls and splashed around topless in the ocean. Then, as Kerr is wont to do, she posted the image to Instagram.

"You're the best @chriscolls @koraorganicsbymk #purenature #freespirit," she wrote as a caption.

This isn't the first time Orlando Bloom's wife has stripped down for the camera. She recently posed topless for Jalouse magazine and flashed her cleavage in a sexy Santa suit around Christmas. Of course, she's probably used to showing off her assets, being a Victoria's Secret Angel and all.
