Christie Brinkley has returned to the pages of the Sports Illustrated swimsuit issue at the age 63 , appearing alongside her two daughters.

The model first appeared on the cover of the swimsuit issue in 1979.

In an Instagram post, she thanked the magazine "for sending the powerful message that good things come in packages of every size and we do not come with an expiration date."

In the issue coming out this month, Brinkley, in a black bathing suit, appears with 31-year-old Alexa Ray Joel, her daughter with singer Billy Joel, and 18-year-old Sailor Brinkley Cook.

Brinkley, who appears to walk on water in the shoot, joked in her Instagram post: "Oh and My kids think I walk on water, so let's not mention the apple box concealed just under the surface."


She told People magazine she 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.

Sports Illustrated said Brinkley is "out to prove that age is nothing more than a number".
