Heidi Klum was showing more than she wanted in an Instagram post that didn't go as planned. While whipping her head around, showing off some new white lingerie, Klum exposed a nipple. It's unknown whether the America's Got Talent judge was aware of the mishap, but she kept the photo and captioned it, "MOOD", replacing the O's with smiley faces. 

Some believe she may have done it on purpose because she is known for being body positive and daring to push the boundaries of fashion.

This isn't Klum's first wardrobe malfunction. Being a model, she is known for wearing revealing clothing and some dresses have been known to expose a nipple every now and then. 

One thing is for sure, and it's that Klum doesn't seem to mind much about showing off her body.
