Sports Illustrated

This year's cover sees the 63-year-old posing alongside her two daughters - Sailor Brinkley Cook, and Alexa Ray Joel.

Writing on Instagram, Brinkley said: "Thank you Sports Illustrated for sending the powerful message that good things come in packages of every size and we do not come with an expiration date!"

Christie appears to be literally walking on water in the photo - something she referred to in her Instagram post.

"The only pressure that I feel is to continue to represent women of all shapes and sizes in a correct manner," she said. "I think that I'm doing that by eating healthy, working out and staying true to who I am. I am a very curvy, voluptuous woman."

Graham, who was featured on the 2016 cover of Sports Illustrated's swimsuit edition, has been vocal about her experiences being body shamed -- no matter her size.
