Christie Brinkley is returning to the pages of the Sports Illustrated Swimsuit issue at age 63, the model announced on Tuesday.
Brinkley will appear alongside her two daughters, 31-year-old Alexa Ray Joel, her daughter with singer Billy Joel, and 18-year-old Sailor Brinkley Cook, in the issue coming out this month.

In an Instagram post, Brinkley thanked Sports Illustrated "for sending the powerful message that good things come in packages of every size and we do not come with an expiration date".
Supposed powerful messages aside, the picture of the trio shows Brinkley and her daughters standing in the water in black swimsuits, with Brinkley seemingly hovering above the surface.
"My kids think I walk on water, so let's not mention the apple box concealed just under the surface," she joked on Instagram.
Brinkley told People magazine she had thought her days of posing in a bathing suit were over when she turned 30, but getting to pose with her daughters convinced her to do it again.
"My first thought was, 'At my age? No way!'" she told People. "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!'"
Brinkley first appeared on the cover of the Swimsuit Issue in 1979.
She proceeded to appear on the cover of what is consistently the magazine's highest selling issue for the next two years.
Traditionally featuring young, thin supermodels, Sports Illustrated seems to have begun considering a (slightly, very, very slightly) greater variety of women for inclusion in its Swimsuit Issue.
Last year's issue featured plus-size model Ashley Graham on one of its three covers. (In 2015, Australian model Robyn Lawley became the first "plus-size" woman to feature in the issue.)
It also saw mixed martial arts fighter Ronda Rousey appear in its pages, wearing a black and white "swimsuit" made entirely of body paint.
