Aubrey O'Day Flaunts Her Perfectly Round Buns in Topless Selfie(IG Go Crazy)

You've really got to love Aubrey O'Day's Instagram.  

The sexy singer has one of the most well proportioned curvaceous celebrity bodies out there, and she's very comfortable in her own skin, so her fans are often treated to tasty eye-candy flicks of her goods.  Most recently, Aubrey took the time out of her day to snap a juicy booty selfie while tanning under the sun.  As she lay out topless on her stomach, the camera captured an amazingly seductive picture of her gorgeous physique in full, with her perfectly round buttocks resting nicely in the background.
