The 63-year-old supermodel landed the coveted front page of the publication three years in a row in the 1970s, marking her breakthrough in the industry. Now she’s back on top form and has her girls Alexa Ray Joel, 31, and 18-year-old Sailor Brinkley Cook by her side.

Posing in the sea, Christie stands in the middle of the photo wearing a black netted swimsuit as she appears to be walking on water, while Alexa poses to her right in a black lace bikini with fringed sleeves and Sailor wears a small black two-piece to her left.

A gorgeous sandy beach acts as a backdrop and Christie couldn’t wait to share the sexy snap on her Instagram page.

“Yes! I am excited to announce that I am back in @si_swimsuit ..I figured with my gorgeous daughters@alexarayjoel and @sailorbrinkleycookby my side whose going to be looking at me!” she wrote in the caption, joking her kids think she walks on water whereas in fact she’s standing on a box in the shot.

“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! (ps. I) can’t wait to see everyone at VIBES on Feb 17th and 18th in Houston! #proudmomhere!”

Entertainment Tonight has shared photos from the spread too, showing blonde beauty Christie sizzling in a hot red bikini as she leans onto a tree, and in another shot Sailor smoulders at the camera with flowers in her hair wearing a tiny green two-piece as she lies on a wooden bench.

Speaking to People magazine, Christie – who has also worked for the likes of Chanel and Revlon – admitted she was shocked when she was approached to return to Sports Illustrated.

“My first thought was, ‘At my age? No way!'” she laughed. “But to get to do it with my girls, I thought, ‘One last go!'”
