Bucket Hat Baby

Sailor picked up her famous mom’s knack for trend-setting before she even learned to walk! Clad in a pink-and-green bucket hat, she and Christie shared some sweet cuddles back in the day. “Here’s to another year we get to spend by each other’s side,” she wrote in a birthday tribute to the supermodel in February 2016. “Thank you for your years of unconditional love and unfiltered happiness. You are the smiles on all of your children’s faces, you are a blooming flower in the middle of winter, you are sunshine. I love you I love you I love you and I hope you never forget that!!!!”

Mama’s Mini-Me

With her blonde hair and bright blue eyes, Sailor has been a dead ringer for her cover girl mama since she was just a little girl – and their resemblance has only grown more striking over the years. “I can’t tell which one is which!” fans often exclaim in Instagram comments on more recent photos of the pair — a tried-and-true flattery that feels particularly apt when you compare photos of Sailor to ones of Christie (or even more so, of her mother!) at the same age.

Sucker for You

“Mama, You taught me how to look at the world every day with such appreciation, as if i’ll never see it’s [sic] beauty again,” Sailor began her Mother’s Day tribute to her super-mama on Instagram in 2018. “You raised me to value the true power of care, of art, positivity and LOVE. You gave me a life filled with health, strength and promise and not a day goes by that i’m not grateful for it.”

Messy Hair, Don’t Care

From the tousled blonde locks to the twin tongue-out poses, the duo looked more like sisters than ever in this blurry selfie from 2015. “My mom is no cookie cutter mother,” Sailor wrote in a separate post that celebrated her relationship with the Sports Illustrated Swimsuit model. “She’s not traditional and she’s not normal. She’s unique and fun and imperfect and beautiful and that’s why I love her so much,” she continued, adding, “She makes peace with mistakes and she loves turning experiences into great stories. She’s fun and colorful and vibrant and everything but boring. I love her so much.”

Cheers to You!

To celebrate her baby’s big 2-1, Christie threw her a bash overlooking the Manhattan skyline at Cecconi’s Dumbo in Brooklyn. The proud mama also wrote a poem championing her daughter and the woman she’s become, which she shared on Instagram.

“21 years around the sun has warmed your heart of golden rays / Cause in those years you have had every kind of day / crushing ones and some ecstatic and while sometimes life May seem erratic…/ it all adds up, expands your heart and makes you who you are today…/ someone I’m so proud of in every single way! / Yes in 21 years you have learned a thing or two / Especially how to make the world a better place just by being being you !”

Sailor Saves the Day

After Christie fell during Dancing with the Stars practice and broke her arm “into a thousand little pieces,” Sailor stepped in to take her place in the competition. While the mother of three was devastated about not being able to perform, her “crushing disappointment” was made easier by her daughter joining the show and learning her routines in just three days! “They popped her into my costumes. They fit her perfectly,” her mom told PEOPLE.

Beach Blondes
