"A lotta people refer to me as an a–," she captioned the cheeky image.

Bethenny has come under fire in the past for her skinny figure, and while ~haters gonna hate~, most of her fans praised how wonderful her body looks. She underwent a "mystery surgery" last year — which In Touch exclusively reported — which may have contributed to her changing figure.

"Bethenny had to have fibroids removed because of concern that if it wasn't taken out, she would develop cancer. The surgery was supposed to be very easy, but Bethenny did suffer from excessive bleeding afterward. It was a scary time for Bethenny," a source said at the time.

Prior to that, the Bravolebrity came under fire for posing on Instagram while wearing her daughter, Bryn's pajamas. The child was only four at the time.

"This is my daughter's nightgown and PJ shorts," she boasted at the time. "Think we're ready to start sharing clothes yet?"
