Christie Brinkley's look-alike daughter Sailor Brinkley-Cook, 27, poses for sexy swimsuit snaps

Christie Brinkley's daughter Sailor Brinkley-Cook looked like the spitting image of her supermodel mother in her latest social media post.

On Wednesday, the 27-year-old blonde beauty uploaded another series of sexy swimsuit photos for her over 200,000 Instagram followers to see.

Sailor looked sensational in a tiny blue bikini as she posed on the edge of a pool during a recent tropical getaway.

The New York-based model stretched out by the water, flashing her toned tummy and legs, with a bush of vibrant pink flowers as her backdrop.

Sailor appeared makeup-free and her long blonde hair was worn down and damp.

Reminiscing about her vacation, Sailor admitted in her post's caption that she was 'mentally still here.'

She added emojis of a pink hibiscus flower and a thought bubble cloud.

Sailor is the youngest of three children Brinkley has and one of two she shares with her ex-husband Peter Cook. 

Brinkley shares her eldest child Alexa Ray Joel, 40, with her second husband Billy Joel. 

She and the Piano Man singer were married from 1985 to 1994. 

Brinkley's first marriage was to Francois Allaux from 1973 to 1981 and her third was to Richard Taubman from 1994 to 1995. Cook was her fourth husband. 

The supermodel was previously married to Cook from 1996 to 2008, welcoming a daughter and one son with Cook.

Their marriage ended due to his infidelity many years before he went on to marry his new wife, college graduate Alba Jancou — who is around the same age as Sailor. 

The 67-year-old married Jancou, who is roughly 39 years his junior, in 2023. 

In addition to Sailor, Brinkley and her ex-husband are also parents to Jack Paris Brinkley-Cook.

The supermodel had Jack with Taubman but their son was later adopted by Cook.

Sailor's recent bikini snapshots have sparked comparisons to her mom and had fans doing a double take — just shortly after the mother-daughter duo revealed that they had previously matched with the same men on a dating app. 

Brinkley opened up to actress Kristin Davis on the Are You a Charlotte? podcast in August 2025 and said that she and her youngest daughter have more in common than their genetics. 

The nepo baby, who is not only has the supermodel as her mother but has Billy Joel as her godfather, had previously signed up her mother on a dating app and conducted a so-called experiment.

In the end, Brinkley recalled that her daughter had 'wanted to see what kind of guys [would match] … and she put me up there … and she said, "Mom, you're right not to go on it, because the same guys that said yes to me, are saying yes to you."'
