The star enjoyed some cuddle time with her dog, tanned while stretching, and also snorkeled.
Fans flocked to the comments to cheer Heidi on. One person wrote: "You are so beautiful Heidi," while another added: "Looking good at 53."

This isn't the first time that the model has flaunted her youthful appearance online in a plethora of bikinis, being that Heidi passionately loves spending most of her downtime beachside.
Heidi's take on wearing bikinis at any age
When Heidi was 44, she opened up about how she'll never let her age stop her from wearing what she wants as she gets older, including bikinis.
She revealed to W Magazine: "For me personally, not much has changed. I still wear triangle bikinis that I have in the past—and most of the time bottoms, not even tops. You are who you are, and I'm always going to be more of a free-spirited person and more open with my body."

Heidi believes that her body acceptance originated from her childhood.
She added: "I've never been really shy with my body, and I think that's also due to the way I grew up. Let's say I was at home and walked into my parents' bedroom and they were changing—they wouldn't be like, 'Oh my god, close the door.'"

It's just very natural."
Like mother, like daughter – Heidi grew inspired seeing her mother's bold confidence, and she embraced her mom's open mindset into her own life.

She concluded: "So if I'm 25 or in my thirties, or now in my forties, it doesn't really change just because I have a different age now. Do you know what I mean? It's kind of just a way of living and being."
