Christie Brinkley's Bikini Photo Is Giving Us Major Swimsuit Envy

Fun in the sun!

Christie Brinkley recently took a tropical vacation with her family and by the looks of it, she had a fabulous time.

The 61-year-old model took to Instagram to post snaps from her trip (including a sexy bikini shot), while sharing some of her best beauty secrets .

"I am wearing Neutrogens Wet Skin broad spectrum. And I always have a hat!!" she wrote on Instagram while posing in a purple bikini.

"I used my skin quenching Recapture Day Cream +IRDefense. Then on top, I put SmashboxCamera Ready Broad spectrum SPF 35 color Medium and Hourglass Radiant Bronze Light just to add a sunny glow," she captioned another photo.

Another shot shows the blond beauty with her 17-year-old daughter, Sailor, and friend Gabby Westbrook in snorkelling gear.

The "Timeless Beauty" author recently told ET that she is no longer a "fan" of Botox and "won't ever do that again."

"I didn't like the claustrophobic feeling of not being able to do whatever I want with my eyebrows," she explained.

She also added, "How you eat and how you exercise, these all play a tremendous role in how you feel, and therefore, how you look. And a smile will give your face an instant lift and it also releases endorphins."

Clearly, it's working for her. Looking good, Christie!
