Back in 1981, Christie Brinkley secured her spot as one of the most iconic supermodels of all time. It was that year that Brinkley graced the cover of the Sports Illustrated Swimsuit Edition for the third consecutive year, making her the first-ever person to do so. Now, the supermodel is also a supermomma, and she's showing her two daughters around her old stomping grounds in a gorgeous photo shoot for this year's Sports Illustrated Swimsuit Edition. Take a look at the stunning mother-daughters photo below.

In her Instagram post to share the beautiful new family photo, Christie Brinkley shared her excitement at posing alongside her daughters Alexa Ray Joel and Sailor Brinkley Cook. She also poked a bit of fun at how the unnatural looking water, which both Joel and Cook are partially submerged in while Brinkley is standing on its surface, writing "My kids think I walk on water, so let's not mention the apple box concealed just under the surface." The supermodel also thanked Sports Illustrated for showing that beauty does not come with an expiration date, referencing the fact that she's 63 years old and still looks absolutely incredible in her swimsuit.

But Christie Brinkley wasn't the only one to share her excitement about the photo shoot on Instagram. As PEOPLE pointed out, both Alexa Ray Joel and Sailor Lee Cook took to Instagram after the shoot to write about how the experience had helped them embrace their bodies and spread a message of body positivity to other women.

Alexa Joel, 31, a singer and the only daughter of Billy Joel, wrote that she struggles to embrace herself fully every day, but this shoot helped her with that. She goes on to say that she hopes to inspire self-love and self-respect in every woman willing to listen to her.

Sailor Brinkley Cook, the 19-year-old daughter of architect Peter Cook, went into more detail about her struggles with self-acceptance in her post. She writes that she had always found something dissatisfying with her changing body growing up, but has come to love her body and now finds the way that it grows and changes to be beautiful.

I've had issues with my body image since before I can even remember. I grew up not loving how I looked and felt held back because of it. I don't know why I always felt that way, sure I had baby fat and definitely went through a plethora of awkward phases, but I had a family that loved me i had friends who made me laugh etc. But for some reason I still looked in the mirror and always somehow found something to pick on. I went from being "too fat" to "too thin" to "too muscular" and I never felt satisfied. My body and I have been through it all. But recently I have been liberated. I am healthy, i treat myself well, and for that i'm happy. I've looked in the mirror and been able to LOVE the things about my body that beauty norms deem 'undesirable'. I now have grown to know that my body is worthy of so many great things. I don't need to be a size 0 to believe in myself. My body carries me each and every day, it loves the people i love, it holds what makes me healthy and strong, it bends it shakes it runs and it CHANGES. That is okay and that is beautiful. I could not be more grateful to the beautiful and strong @mj_day for including me in this years Sports Illustrated Swimsuit Issue ????????? This is more than a magazine to me and always has been. As a growing young woman SI showed me all bodies are different and all bodies are worthy of celebrating. Thank you thank you @si_swimsuit for celebrating my beautiful mama, my beautiful sister, I, and ALL WOMEN!! How lucky am i?! ???????????? i think I'm dreaming. ???????????? thank you!!!!!!! ? (Also, thank you @hayleythorpeholla and @v_beast and everyone at @dogpound for changing my life ?????) More to come!!!!!!!!
