Complete with letter beads that spelled out "hot."

We might be approaching winter but Kourtney Kardashian is still out here heating things up. The reality star gave us a glimpse at her envy-inducing, tropical getaway with fiancé Travis Barker, which included a super tiny swimsuit.

On Sunday, Kardashian posted a carousel of images to Instagram from her luxurious trip to Cabo San Lucas, Mexico. The first image of the post was a mirror selfie taken by the social media star in a string bikini. Kardashian stood on her tip toes while showing off the red and ivory suit with tiny bottoms held together practically by a thread.

The avant-garde design featured three little letter beads in the middle of the top that spelled out the word, "HOT."

In a second image, Kardashian shared another selfie while lounging in the sun with a pair of black rectangular shades. Meanwhile, the rest of her post featured gorgeous snapshots of the ethereal-looking beach resort.

"La romántica," Kardashian captioned the gallery, which translates to "The Romantic." It appears the getaway was in celebration of Barker's 46th birthday on Nov. 14 — complete with horseback riding and a private screening of Home Alone on the beach.
