The 31-year-old model has admitted she is going through a ''weird phase'' where she feels ''jealous'' of every woman who boasts a super toned physique, and she can't help but compare her body to others, which leaves her feeling ''inadequate'' to the point she runs to her 38-year-old spouse in floods of tears.
Speaking at a Beautycon event in Los Angeles, which has been reported on Hellogiggles.com, the brunette beauty said: ''I'm in a weird phase where I'm jealous of those bodies.
''My old ass will go on social media, and I will look at the Photoshopping, Facetuning, and the apps -- and everything that goes into creating what is now a hit Instagram photo -- and I feel insanely inadequate,'' Chrissy said.
''There have been times I've cried to [husband] John [Legend], where I felt like I would just never have 'that' body. I've definitely been really upset with ... you know, everyone has a butt now, everyone has curves, and a little waist, and that's not me.''
The style icon is desperate to be ''cool'' with her shape and be an inspiration to other women.
She said: ''But I also really want to be cool with my own body. I really want to be that person for you all, that says, 'You don't need that f**king s**t.'''
But the 'Lip Sync Battle US' co-host - who has 18-month-old daughter Luna with the 'All of Me' hitmaker - is comforted when she sees other people naked and notices they too have stretch marks.
She explained: ''I've been on shoots, I've been naked-to-naked with people, and I will say that everyone has a stretch mark. Every time I see that other stretch mark, I'm like, 'Girl, yes!' It makes me feel better, and if more of us did that kind of shit, how many people would feel better?''
It's time for a riot grrrl revolution.
