"Oh f--- no!" the Oscar-winning actress exclaims.
Besides not getting hung up on aging in Hollywood, Kate -- who gave birth to her third child, Bear, last December -- is also refreshingly not in any rush to lose the baby weight at seemingly impossible speed.
"There's a big part of me -- now, more than ever before -- that feels a sense of responsibility for how other women view themselves," the Divergent actress explains. "Take having the baby, for instance. Have I actively been on a diet to lose my baby weight? No, I haven't. I genuinely bloody haven't. I so didn't want to be one of those, 'Oh, wow, she's back in shape after 12 weeks' women. When I read things like that I just think, oh, for f**k's sake, that's actually impossible."
And she's definitely not stressing about getting her pre-baby body back.
"Life is just too short to be spending time focusing on things like that," she says. "I want to keep my health and my sanity and be well fed and happy. I was nowhere near my pre-pregnancy shape when Bear was 12 weeks old ... And you know what? My body will never go back to what it was, and I wouldn't expect it to after three babies."
Keeping up with Hollywood beauty standards has been in the forefront since Renee Zellweger made an appearance at ELLE's 21st Annual Women In Hollywood Celebration in October, looking almost unrecognizable due to suspected plastic surgery.
