Kardashian Women Vacation in St. Barts

— -- The Kardashians women have taken over St. Barts.

Pictures of the family vacation have been circulating on entertainment news sites and social media since their arrival earlier this week.

First on their itinerary, some retail therapy.

Kris Jenner and daughters Kim, Kourtney and Khloe Kardashian and Kendall Jenner hit the shops in style.

Kim and Khloe wore all black, while Kourtney opted for white with strappy gladiator sandals to match those of her mom and little sis Kendall.

Later, Kendall and Khloe can be seen goofing off on ATVs.

Khloe posted a black and white glamour shot with two of her sibs, writing, "Real Sisters."

Also along on the Caribbean island vacation are Kylie Jenner, who recently turned 18, Kim's daughter, North West, and Kourtney’s three children, Mason, Penelope and Reign Disick.

Aunt Khloe posted a cute snap of little Nori wearing her mom's oversized sunglasses, along with the caption "MOOD."

That wasn't the only sweet photo of the kids.

Both Kim and Kourtney posted photos of their girls, North and Penelope meeting a mermaid. "Last night we swam with a mermaid," Kourtney wrote.

"Little mermaids," Kim captioned another snap.

Of course, this being the Kardashians, their vacation is not all play and no work.

On Tuesday, Kim, Kourtney, Khloe, all dressed in black, joined mom Kris for an oceanside workout alongside a trainer.

At one point, Kim, who is six months pregnant with her second child, showed off her growing baby bump to photographers when she lifted her shirt to cool off.

Kim wasn't the only Kardashian showing off her midriff. Kourtney was also proud to show off her post-pregnancy bikini bod on Instagram.

Fans will be able to see more of the family's vacation, which is being filmed for their E! reality series "Keeping Up With the Kardashians," when it airs next season.
