Christie Brinkley is counting down to a big month with the release of her debut memoir, Uptown Girl, inspired by her ex Billy Joel's song of the same name.
The 71-year-old former supermodel has been teasing the upcoming release for over two months, first announcing it in early February.
She kicked off a countdown to release date on April 29 with new photos on Instagram, posing on her boat and soaking up the sun in a red string bikini.
The two-piece showed off her toned figure, which she added to with a red, white and blue patterned cover-up and a straw hat, stretching herself out to get some extra rays.
"Feeling Optimistic and hope you are too! Wishing everyone bright sun shiny days ahead! #uptowngirlmemoire drops 29 April," she captioned the photos.
Fans left sweet comments like: "Lady in red sailing by the sea," and: "And you're lookin' hot at 71. Love you to the moon," as well as: "I love that suit and can't wait for summer on the Cape!"

"It will take you my dear readers from my life as a little girl, to cover girl, to uptown girl, and everything in between… with lots of adventures, some magic and some heartbreak along the way. I can't wait to share these untold stories with you."
She continued: "It will be available everywhere and anywhere books and audiobooks are sold on April 29th! (Perfect timing for Mother's Day!)"

"I always had a journal to help me keep track of my busy life…," Christie noted. "What I was doing, where I was supposed to be. I would write down the shenanigans and adventures that took place on modeling shoots all over the world!"
She even said: "Often I included little drawings of everything from friends to cover tries to charming harbors and restaurants where we enjoyed long meals and laughter."

The publishing house notes the book will touch upon "her whirlwind career, her four tumultuous marriages — including her heartbreaking divorce from Billy Joel — and the harrowing experiences (a 1994 helicopter crash) that almost cut her life short."
