And on Monday the former Sports Illustrated proved she practices what she preaches as she shared a bikini photo flaunting her toned tummy, sculpted arms and lean legs as she posed in a two piece while on vacation.

The 61-year-old mother-of-three has been in the Caribbean's Parrot Cay area for her a friend's wedding.

The blonde New Yorker also wore a hat and a tiny green cover up around her hips as she stands on a rocky incline.

The ex-wife of Billy Joel wrote in her caption, 'So excited to make something special with the driftwood I just found (under my foot).'

But instead of mentioning her incredible bikini body, Brinkley instead talked sunscreen.

Perfect your holiday style in a printed bikini by Pucci

Christie Brinkley has got one of the best bikini bodies in the business, so it was no surprise to see her showing off the result of all her workouts on the beach. If we had rock hard abs like hers (at ANY AGE) we would get them out at every opportunity.

Her teeny tiny triangle bikini is by Emilio Pucci and we love the multi-colored geometric print. It's a signature style of the label (it even features a print of the designer's autograph!) and will definitely turn heads on holiday.

Click the link (right) to buy a similar version at Net-a-Porter. Her exact vibrant violet one is sold out. But if you want the Pucci look on a more purse-friendly budget our edit below is here to help you stock up your suitcase.

Asos' blurred lines two-piece is too good to miss, or this Wildfox bikini will do the trick. Simply team yours with oversized sunnies to complete the A-list look.
