Christie Brinkley is soaking up the sun.
The 68-year-old supermodel took to Instagram over the weekend to share a video of herself jumping off of a boat and into the water, while vacationing in Turks and Caicos.
"My happy heart is singing! Grazié mille amici miei! #masquenada," she captioned the video, in which she wears a stunning strapless navy blue swimsuit.
It didn't take long for fans to chime in, praising Brinkley for her care-free post and for looking "forever ageless."
"Look at you! Forever ageless. Love this for you. You look so happy and free-spirited. Really living your best life," one Instagram user commented.
"Never will you age!" added another.
"Still young at heart!" someone else wrote. "Love this energy."
"Amazing, you truly are young at heart," added another fan. "I am 52 and I would be afraid to jump in the water like that! I would probably hurt something."
"You go, girl!" another penned.
"So beautiful and ageless!"
"You're beautiful! I absolutely love your energy (and your swimsuit! So cute)," another commented.
Last month, Brinkley opened up about feeling discriminated against due to her age, and why the term "aging gracefully" should be about more than just looks. She spoke out following the publication of an article that included the star in a list of celebrities over 50 who "prove" that "being older is attractive."
While the article was meant to empower women not to fear growing older, Brinkley worried it focused too much on a woman's ability to remain youthful-looking.
"The expression 'aging gracefully' should not be about one’s looks but about the attitude and energy one offers the world," Brinkley wrote via Instagram. "Looking good is a byproduct of feeling great and showing up in the world with a heart full of good intentions, and good energy!"
"Women of every age belong everywhere they feel like being, and we can do whatever we set our minds to," she continued, adding that any woman can make an impact, regardless of her age.
"We may not always succeed or win, But we’re old enough to learn from our mistakes and keep growing and evolving so we are a force to be reckoned with. There are a million older and wiser women out there reshaping and rebranding the numbers," she penned.
