Brooke Shields talks self image and bunion surgery in the October issue of Shape Magazine.

The 43-year-old mommy of two says she was nervous about donning a skimpy two-piece on the cover of Shape because she hadn’t exercised in two months following an operation on a foot bunion.

“I can’t believe I said I’d do this shoot when I haven’t been able to exercise for almost eight weeks.”

Nonetheless, Brooke managed to boast a completely flat tummy as she graced the cover of Shape’s Special Breast Cancer Month Edition.

The star of NBC’s Lipstick Jungle, who has enjoyed a modeling and acting career that has spanned more than three decades, reveals she suffered from low self-esteem and body insecurities for most of her life.

Brooke was horrified when a dance instructor forced her to watch herself perform in front of a mirror during class to boost her self-confidence.

“I was like: ‘Are you crazy? What if I don’t like what I see?’ I was so tall and never skinny. I just wanted to put my head in the sand and not think about my body.”
