....and she STILL looks hot. Along with her two daughters Christie appears once again in SI swimsuit edition.....40 years after her initial appearance!

Christie Brinkley first covered the Sports Illustrated Swimsuit Issue in 1979 (then set a record by landing the covers for the next two years). For decades thereafter, she toured the world posing in one exotic location after another, before hanging up her barely-there bikinis in 2004. But now, at the age of 63, she’s returning to the SI Swim family, proving her agelessness once again. And this time, she’s brought along two very special guests.

Brinkley is joined by her daughters, Alexa Ray Joel, 31, and Sailor Brinkley Cook, 18, in the magazine, on newsstands Feb. 15, and she says their encouragement was key to getting her back in her bikinis.

“My first thought was, ‘At my age? No way!'” she tells PEOPLE exclusively in this week’s issue. “When I turned 30, I was like, ‘This is the last time I’m posing in a bathing suit!’ When this issue comes out, I’ll be 63. I thought, ‘Those days are over.’ But to get to do it with my girls, I thought, ‘One last go!'”

In the sexy spread, the trio wears coordinating black swimsuits, including a cutout mesh one-piece on Brinkley, as they stand on the shoreline of an idyllic Turks & Caicos beach. Brinkley also poses solo in a number of skimpy two-pieces, including the show-stopping red bikini below.

Sailor, Brinkley’s younger daughter with ex-husband Peter Cook, who has already dipped her toe into the modeling world, says the SI Swim experience was “very empowering and liberating.”
