Tyra Banks isn't perfect -- and she's not pretending to be.

The supermodel, 38, shared several behind-the-scenes pictures from a photo shoot via Twitter and Instagram October 2. "I shot with Mark Liddell when I was a teenager," Banks wrote. "So great to work with him again!"

The blonde beauty wore tight jeans and a denim shirt, which she tied in a knot to expose her sexy stomach. "Check the juicy muffin top on my back!" she wrote in the caption. "Perfect is boring."

Banks has long embraced her imperfections, telling Us Weekly in May, "This is who I am! I'm Tyra Banks and I have cellulite!"

The former Victoria's Secret stunner hopes that by publicly celebrating her flaws, young girls will feel empowered to do the same. "My main mission is to get girls to realize their inner and outer beauty and have high self-esteem with both," Banks explained.

Banks' America's Next Top Model: College Edition airs Fridays at 8 p.m. EST on The CW.
