Crystal Renn, who became a plus-sized model after battling anorexia in her teens, raised eyebrows last night in NYC, when she hit the red carpet looking gaunt-faced and startlingly skinny – and RadarOnline.com has the shocking photos.

The 25-year-old supermodel, who wrote a book about her struggles with an eating disorder called Hungry: A Young Model’s Story of Appetite, Ambition and the Ultimate Embrace of Curves, looked drastically different in her curve-hugging Zac Posen gown at Metropolitan Opera Season Opening Night Performance of Anna Bolena, than she did on the runway just a year ago.

Back in November 2010, Renn, who had enjoyed several successful years as a size-12 plus sized model, revealed that she had lost weight from hiking and yoga, and was down to a size 8 – but from the looks of her body last night, she has dropped several more dress sizes since.

The 5 ft. 9 in. model has admitted that at the peak of her eating disorder, she weighed a mere 95 pounds. In February 2011, after her weight loss started to gain criticism, Renn blasted back on the Ford Models blog that there was nothing to worry about.

"When this whole weight loss thing happened, I think that a lot of people wanted to point their finger at somebody. I think that they wanted to find a conspiracy where there absolutely was none."

But months later and her swerving curves noticeably depleted, she is going to have more explaining to do!
