Christie Brinkley posed for a mirror selfie in a white Alo bra on Instagram on Tuesday.
The model snapped a photo of herself with flexed biceps while wearing a tiny black jacket and leggings.
This came after she celebrated her 70th birthday with a beach vacation.
“When I look in the mirror on my 70th birthday and what do I see,” Brinkley wrote, “I am finally happy with the person looking back at me.”
The mother-of-three looked proud as she smiled broadly for the camera in her spacious walk-in closet full of spring dresses and floppy straw hats.

“When I look in the mirror on my 70th birthday and what do I see,” Brinkley writes, “I am finally happy with the person looking back at me.”
Christie rose to fame when she graced the cover of Sports Illustrated Swimsuit Issues in 1979, 1980 and 1981.
In 1985, the supermodel married Billy Joel and had their daughter that same year. Brinkley collaborated with him on his music videos.
Nine years later, the power couple separated – but she continued to work.
Christie is considered one of the most beautiful women of all time by Allure and Men's Health.
She was the face of Covergirl for over 25 years and had one of the longest modeling contracts of all time.
As a result, she was re-signed as a mature skin model for the company in 2005.
The supermodel has been on the cover of over 500 magazines.
Brinkley made her Broadway debut in 2011 as Roxie Hart in the long-running musical Chicago.
For a 2019 episode, she guest-starred on the NBC series “The Goldbergs.”

The model went on a tropical vacation with 12 of her closest friends to celebrate turning 70.
“I want to inspire women of all ages and body types to confidently wear products that support their individual characteristics,” Brinkley said in December.
Despite being married four times, Christie said in January that she was open to finding love again but felt comfort with “life as it is.”
The model strongly believes that you should find happiness within yourself first.
