Christie Brinkley, 67, is stunning in a strapless swimsuit

Christie Brinkley has become one of the few supermodels who has a very long career.

At age 67, the blonde beauty is still in incredible shape and works often; she has landed another Sports Illustrated Swimsuit Edition cover and is the spokesperson for SBLA BEAUTY Beauty, Cosmetic & Personal Care.

And on Sunday the mother-of-three reminded her Instagram followers how she still looks great in a swimsuit as she shared several images with her 25-year-old son Jack while in the Caribbean.

The cover girl had on a black one piece swimsuit that made the most of her small waistline and long, lean legs.

She added a leopard shirt tied around her waist, a straw hat and red flip flops that matched her toe nail polish. 

‘I’ve got SONSHINE on a cloudy day,’ began the New York resident’s caption as she added, ‘I love you @jackbrinkleycook.’

She also has daughters Sailor, 22, and Alexa, 35.

This comes a week after Christie said ‘ageing is the last frontier’ for the modeling industry.

The model shared that the business has evolved markedly over recent decades, but she still thinks ageism remains a problem.

‘Women tell me that they want to see themselves in there. They want to be stylish but they don’t want to look like they’re trying too hard. They want to be represented,’ noted the cover girl about seeing more mature women in fashion magazines.

‘I’ve been in this industry for 47 years now and I can’t begin to tell you how much it has evolved, but ageing is the last frontier.’

Despite ongoing issues, Christie remains in love with her job and is eager to keep working.

She told The Times newspaper: ‘I’m too young not to be working. I love my job.’

Christie was once told that her career would be over by the time she was 30. 

The shoot was arranged at short notice, meaning she didn’t have time to diet ahead of appearing with her daughters.

Speaking about her approach to the shoot, she explained: ‘I thought, “Well, it’s all about body positivity today, so que sera, sera.” And with those two beauties, who’s looking at the old broad in the middle, right?’

She has also been open about how she has had to get surgery to feel her very best. 

Christie underwent hip replacement surgery last year, after she was injured in a helicopter crash in Colorado in 1994.

The model took to Instagram to share a series of snaps of a snorkeling trip, one of which showed a large band aid covering her hip area.

She captioned the post: ‘New Year, New Hip! Yes that’s a band aid on my hip.

‘I injured my hip in a back country skiing helicopter crash on a mountaintop in Telluride many years ago. The pain in my hip got a little bit worse each year. 12 years ago I was told it needed to be replaced but the surgery was daunting ! And I had things to do!’

Brinkley came to fame in the late 1970s with the Sports Illustrated Swimsuit Issues.

She was on an unprecedented three consecutive covers starting in 1979. 

Her fame only grew when she costarred with Chevy Chase in Vacation and also appeared in Billy Joel’s music video for Uptown Girl, eventually marrying the crooner and welcoming their daughter Alexa Ray.

She also has 25-year-old son Jack Paris Brinkley Cook with Richard Taubman and 22-year-old daughter Sailor Lee Brinkley-Cook with ex-husband Peter Cook.  

The star is now a spokesperson for SBLA BEAUTY Beauty, Cosmetic & Personal Care.
