If you’ve spent any time on social media lately, you’ve probably seen those "twin" photos of Christie Brinkley and her lookalike daughter, Sailor. It’s wild. At 71, Christie still looks like she stepped off the cover of Sports Illustrated, and Sailor basically looks like a time-traveling version of her mom from the 1980s. But there is a lot more to the story of Christie Brinkley's daughter—or rather, daughters—than just good DNA and matching blonde hair.
Most people forget that there are two of them. You have Alexa Ray Joel, the soulful musician who is now 40, and Sailor Brinkley-Cook, the 27-year-old model who has been dominating the runway. They grew up in very different eras of Christie’s life, and honestly, their paths couldn't be more distinct.
The Reality of Growing Up Brinkley
Living in the shadow of a "supermodel mom" isn't all glam and private jets. Christie has actually been pretty vocal recently about how tough it was to raise her kids in the spotlight. On a podcast last year, she called it one of the "biggest bummers" of her fame. It’s hard enough being a teenager, but imagine doing it while people are constantly comparing your face and body to a literal icon.
For Alexa Ray, that scrutiny was brutal. She’s the daughter of Billy Joel, and because she didn't choose the modeling path initially, the internet was—frankly—vicious about her not looking exactly like her mother. She’s talked about how "excruciating" that media pressure was.

Sailor had it a bit different. She’s the "spitting image" of Christie, which comes with its own set of weird pressures. People expect her to be Christie 2.0. But if you actually follow her, you’ll see she’s way more focused on mental health advocacy and body positivity than just being a "pretty face."
Alexa Ray Joel: The Piano Man’s Daughter at 40
Alexa just hit a major milestone—she turned 40 on December 29, 2025. It’s kinda crazy to think the "Uptown Girl" baby is now a veteran in the music industry. She’s spent nearly two decades carving out a space for herself that has nothing to do with runways.
Her vibe is very New York jazz meets soulful pop. She’s not just "Billy Joel’s kid"; she’s a legitimate pianist and songwriter. She recently released a single called "Heavy Eyes," and there’s a new music video dropping this month (January 2026).

Sailor Brinkley-Cook: More Than a Lookalike
Then there’s Sailor. At 27, she’s the one most people think of when they search for Christie Brinkley's daughter because they do those viral "twinning" shoots together. They even once admitted to matching with the same guys on dating apps because of their age-defying looks. Awkward, right?
But Sailor’s career is actually quite intentional. She started modeling at 15, but she’s been very open about her struggles with body dysmorphia. Christie actually gave her some solid advice early on: if the industry wants you to be dangerously thin, don’t do it. Use your brain.
Sailor is also the one who stepped in for her mom on Dancing with the Stars back in 2019 when Christie broke her arm. That was a huge turning point for her. She was terrified of being on TV, but she did it anyway. That "spunky, bold" energy is what defines her today.

What Most People Miss About the Family Dynamic
The coolest thing about this family isn't the fame; it's how much they actually seem to like each other. You often see them all together at their home in the Hamptons. During Christmas 2025, Christie shared photos of them all singing "Silver Bells" and "Silent Night" together. Alexa and Christie were dueting while Sailor filmed the whole thing.
They aren't just a "celebrity family" for the cameras. They seem to have this genuine, protective bond. When Alexa faced online bullying, Sailor and Christie were the first to jump in. When Sailor was nervous about a shoot, Alexa was her go-to for advice.
Actionable Insights for Following Their Journey
If you’re interested in following the next chapter for Christie Brinkley's daughter, here is what to keep an eye on:
- Watch for Alexa’s New Video: The "Heavy Eyes" music video is slated for a January 2026 release. It’s expected to be her most "vulnerable" work yet.
- Follow Sailor’s Advocacy: She’s becoming a major voice in the "health-first" modeling movement. If you're into fashion that isn't about size zero, her Instagram is a must-follow.
- Check out the HBO Documentary: If you want to see the family's history from a raw perspective, Billy Joel: And So It Goes features extensive interviews with Alexa about her childhood.
The bottom line? Neither Alexa nor Sailor is trying to be a carbon copy of Christie. They’ve taken the "family business" of being in the public eye and turned it into something that actually feels authentic to them.
