They look like sisters! Christie Brinkley, 67, appears youthful next to her mini-me model daughter Sailor Cook, 23, while at a Michael Kors event

Christie Brinkley has managed to stay youthful looking at the age of 67.

And this weekend the Vogue cover girl accomplished the nearly impossible feat of appearing to be around the same age as her youngest daughter, Sailor Cook, 23 (the model also has daughter Alexa Ray, 35, with Billy Joel).

The blonde ladies posed side by side while at a private event for fashion designer Michael Kors.

'Celebrating 40 years of the iconic American Style of the adorable legend @michaelkors in the chicest garden of hosts extraordinaire Jon and legs for days @tizzielisch and co hosted by the lovely and glamorously cool @naomiwatts plus strawberry shortcake all on a gorgeous Summer night!' said Christie in her Instagram caption.

'Thank you all for including @sailorbrinkleycook and me! PS Thank you @owengould for our new haircuts!'

The siren finished with 'here's to 40 more! At least! ❤️.'

Christie had on a white halter dress with a beige belt and light green jacket on her shoulders. Sailor wore a brown sequined dress with a belt. 

This comes after the Sports Illustrated Swimsuit Edition model was radiant on the July cover of Social Life magazine in a stunning blue dress that made the most of her 25in waistline.

The 5ft9in blonde bombshell seemed to be completely wrinkle free as she added several rings from Judith Ripka.

She has been modeling since the 1980s and became famous when she played the femme fatale in Vacation opposite Chevy Chase then went on to marry crooner Billy Joel. She still has a busy modeling career to this day.

On the cover the Uptown Girl star wore a skintight royal blue dress with rings from New York jeweler Judith Ripka.

The gold and silver bands sparkled as the model flashed a bit of leg.

Inside she modeled dresses by 70s icon Halston. One was white with a keyhole in front showing off her cleavage.

Last year the catwalk vet posed for the same magazine in a blue swimsuit.

The looker has three children: singer Alexa, 35, and model Jack Paris Brinkley Cook, 26, and Sailor, 23.

Earlier this year she said having a hip replacement was 'really depressing'.

The model revealed in January that she had undergone a hip replacement to fix an injury from 26 years earlier, when she was in a backcountry skiing helicopter crash.

And now, Christie has explained the operation made her feel 'old', and left her upset at the thought of getting older.

She said: 'I started feeling like, 'Oh my gosh, this is how you get old'.

'It was really depressing so I thought, you know what, I'm going to start to whittle away at it. I'm going to do whatever it takes. I'm going to start to whittle away at this and I thought the hip is what scares me the most. Let me check in on the hip.'

But after having the surgery, Christie couldn't be happier with the difference it has made to her life.

Offering her advice to anyone else who is putting off medical care, she told the 'Dr. Oz Show': 'I tell you for people at home, go speak to the doctors. Find out what they can do for you. You know the more you learn about it the less afraid you will be and don't be afraid because you know what these surgeries can do now. The way they have perfected them is really amazing.'

The beauty's comments come after she previously marked her birthday in January by revealing the huge difference her hip surgery had made. She wrote on Instagram at the time: 'I am overjoyed to be able to move my body again. I am getting stronger every day, and I like think I'm ready for anything ... a hike, swim dive, paddle, ride, ski and even a big piece of birthday cake! Hey I can work it off!'
