The 47-year-old actress said people would not be talking about her that way if she were a man, reported People.

"I've never seen the maturation of a woman as a negative thing. I've never seen a woman stepping into her more powerful self as a negative.

"But this conversation perpetuates the problem. Why are we talking about how women look? Why do we value beauty over contribution? We don't seem to value beauty over contribution for men. It's simply not a conversation," she said.

Zellweger was highly criticised for her appearance when she came back in the industry in 2014 after two years of break as many rumoured that she had a plastic surgery.
