How is Christie Brinkley 63 years old?! The stunning supermodel is making headlines this week for posing nude (yes, totally naked!) for a gorgeous new magazine spread.

In one pic from Social Life magazine‘s July 21 issue, Christie modeled sans clothes on a Hampton’s beach while covering herself with only a giant palm leaf. The photo perfectly shows off the actress’ undeniable beauty as she rocked tousled, long, blonde locks and dark, smokey eye makeup.

During a recent interview, the mom-of-two admitted she loves wearing only a bikini while lounging around her house — and even gardens in a bathing suit! “I always put a bikini on and say, ‘Oh, it is just to wear around the house. I am not going to go anywhere in it. I just want to get a little color while I am gardening,'” she told PeopleStyle. “I run around trimming my begonias to even everything out so I don’t have any tan lines.”

“When you’re naked, you want those parts tanned! I don’t care how much sunblock you put on, when you’re outdoors as much as I am, you’re going to get some color,” Christie confessed. “You know what? You can’t really critique a person over 50 — it is just like, if they are brave enough to put on a bikini then you let them be!”

Earlier this year, Christie similarly turned heads when she and her two daughters, Alexa Ray Joel and Sailor Brinkley-Cook, posed together in the latest Sports Illustrated Swimsuit Issue. “Yes! I am excited to announce that I am back in @SI_Swimsuit… I figured with my gorgeous daughters, @AlexaRayJoel and @SailorBrinkleyCook, by my side, who’s going to be looking at me?” she wrote on Instagram at the time.

“Oh, and my kids think I walk on water, so let’s not mention the apple box concealed just under the surface… Thank you, 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!” the proud mom continued.
