Christine Brinkley Still Stuns at 71 in Red Hot Bikini During Boat Ride, Teasing Her Upcoming Memoir

Christine Brinkley turned heads once again this weekend, sharing a radiant moment with fans as she enjoyed a sun-drenched boat ride.

The 71-year-old supermodel took to Instagram Sunday to post a series of glowing selfies while sporting a vibrant red bikini, offering a glimpse of her timeless beauty and positive spirit.

“Feeling optimistic,” Brinkley captioned the sunlit snaps, where she paired her swimwear with a breezy red cover-up and accessorized with two stylish hats.

Exuding beach-day glamour, the former Sports Illustrated Swimsuit cover star beamed for the camera, adding a cheerful message to her followers: “Wishing everyone bright sun shiny days ahead!”

In true Brinkley fashion, the post was not only about sun and style — it also served as a nod to her upcoming memoir, Uptown Girl, which is set to hit bookshelves on April 29.

Brinkley first unveiled the memoir’s title and cover in February, with publishing house Harper Influence, an imprint of HarperCollins, describing the book as a candid look at the icon’s “whirlwind career.”

But Uptown Girl is more than a journey through fame — it’s also a deeply personal account of her life, including her “four tumultuous marriages” to François Allaux, legendary musician Billy Joel, Richard Taubman, and Peter Cook.

The book also delves into Brinkley’s role as a devoted mother.

She shares daughter Alexa Ray Joel, 39, with Billy Joel; son Jack, 29, and daughter Sailor, 26, with ex-husband Peter Cook.

Through all of life’s highs and lows, the model-turned-businesswoman has emerged with a message of resilience, self-expression, and positivity.

“I wrote this book to inspire readers to create the life they want,” Brinkley shared in a statement.

“I’ve always tried to do [that] — not through fortune or fame, but by saying yes to adventure and trying to find the magic in every moment, no matter how big or how small.”

Brinkley’s social media moment this weekend reminded fans of exactly that: optimism, beauty, and the joy of living fully at every age.

And as Uptown Girl prepares to make its debut, fans can look forward to a more intimate look into the life of a woman who, even in her seventies, continues to redefine what it means to shine.
