Age is clearly just a number for Christie Brinkley!
The 63-year-old model is starring alongside her two daughters, Alexa Ray Joel, 31, and Sailor Brinkley Cook, 18, in the new Sports Illustrated Swimsuit Issue — and the trio look absolutely stunning in the family snapshots!
Christie revealed her fun return to SI via Instagram on the evening of Monday, Feb. 6. "Yes! I am excited to announce that I am back in @SI_Swimsuit… I figured with my gorgeous daughters, @AlexaRayJoel and @SailorBrinkleyCook, by my side, who's going to be looking at me?" she wrote.

"Oh, and my kids think I walk on water, so let's not mention the apple box concealed just under the surface… 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!" the proud mom continued.
Christie welcomed daughter Alexa Ray in December 1985 with her second husband, Billy Joel, whom she was hitched to from 1985 until 1994. Sailor's dad is the star's fourth husband, Peter Cook. The two were previously married from 1996 until 2008 and had their daughter in July 1998.
The National Lampoon's Vacation star additionally has a 21-year-old son, Jack Paris Brinkley Cook, with her third ex-husband, Richard Taubman.

Following the pic's release, Sailor also shared the gorgeous new SI photo of herself with her mom and sister via her Instagram page. "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," she wrote. "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."
"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," Sailor continued. "Thank you, thank you, @SI_Swimsuit, for celebrating my beautiful mama, my beautiful sister, I, and all women! How lucky am I?!"
