It looks like Kourtney Kardashian just trumped sister Kim in the unofficial Kardashian belfie competition. The mom of three found some time to slip into her swimsuit while vacationing with friends in Iceland to celebrate her 37th birthday, and their hot tub adventure led to a sexy, wedgie photo op.

In the snap, Kourtney is seen climbing out of the hot tub in the Issa De’ Mar “Makena” surf suit, which retails for $180 and features slashed side panels and a “cheeky cut.” She captioned the photo with a very simple “Eski-ho.”

The star was joined in the hot tub by friends Simon Huck, Steph Shepp and Nicole Reda.

The birthday girl spent most of her trip on top of ice-covered mountains in fur coats, so it was only a matter of time before she ditched all the layers for a swimsuit.

Her latest butt-baring moment comes just after a slew of sexy Instagrams for the star. Catch the highlight reel below.
