While the surgery was motivated by health fears, Sidibe is no stranger to body-image issues.She told People shes learned to embrace her body , no matter what sizing she may be.

Theres nothing ugly about me. Anyone trying to convince me that I am and its usually me is wasting her hour, she told People. I was in a war with my body for a long time. If Id started treating it better sooner, I wouldnt have expended so many years disliking myself. But I love my body now.
