Kourtney Kardashian Calls Herself an 'Eski-Ho' in Booty Shot From Iceland Trip

Even a snow-covered country can't keep the Kardashians from flaunting their assets! On Tuesday night, Kourtney Kardashian posted a sexy shot of her hourglass figure in a black cutout swimsuit. The cheeky Instagram highlights the birthday girl's curvaceous booty.

"Eski-ho," she captioned the fun pic.

Kourt also snapped a shot, chilling in the Blue Lagoon Spa with some pals wearing her black long-sleeved suit. Her younger sister Kim Kardashian was nowhere to be seen, but the siblings have been pretty inseparable throughout their trip to Iceland.

Earlier in the day they posed with Kim's hubby, Kanye West, and producer The Dream atop a snow-covered glacier. Kourtney also shared a funny pic chatting with Kim, using the caption, "Do you want to build a snowman?"

The group celebrated the eldest Kardashian's 37th birthday on Monday and took a helicopter ride over the picturesque landscape. Though they had to make a brief "emergency landing" on a golf course due to a stray seatbelt, the family seems to be having a fabulous time, posting and Snapchatting up a storm.
