Even the Material Girl feels less than perfect sometimes.

At the Met Gala in New York on Monday night, Madonna confessed to reporters that she wasn't thrilled with the way she looked.

"I feel fat in my dress," she said.

The 52-year-old mother of four looked extremely fit in her blue Stella McCartney dress. She paired the gown with Sergio Rossi heels and Cartier jewelry.

The chiseled star, famous for her macrobiotic diet and intense workout regime, even opened a Hard Candy gym in Mexico City and has plans to expand the franchise to more than ten locations worldwide.
