Elizabeth Hurley, who is currently vacationing in India, took to Instagram on Thursday to give fans a peek at her relaxing getaway while also showing off her incredibly fit figure.

In one of the pics, the 51-year-old model, clad in a hand embroidered blue string bikini and oversized sunglasses, put her abs on full display, posing in front of crystal clear water.

"Life is short, buy the bikini," she captioned it, tagging her swimwear line, Elizabeth Hurley Beach, and her 14-year-old son, Damian Hurley, who snapped the photo.

It appears Elizabeth has been having a blast in India, captioning another photo, "Wish you were here."

And while Mom was showing off her hot bod, her son just wanted to let his followers know he's finally catching up to The Royals star's height. "Think it's safe to say I'm taller @elizabethhurley1," he wrote alongside a photo of the two standing next to each other.

Too cute!

When ET caught up with Elizabeth in December, the proud mama couldn't stop gushing over her look-alike son, who made his acting debut on The Royals just a few days after our interview.

"[He] has turned out to be tall, dark, handsome and talented, so he was perfectly cast as Prince Hansel," she dished. “Damian is very charming in real life, so it was a hoot for him to play someone so obnoxious."
