Kim Kardashian’s daughter North West and Kourtney Kardashian’s little one Penelope Disick were seen having a fun time with a woman dressed as a mermaid during a vacation on the Caribbean island of St. Barts.

Kim posted a photo of the two kids dressed as mermaids standing by the pool and looking at the woman.

Newly single Kourtney also posted a picture by the pool and was seen in a tropical bikini and bandana.

On Tuesday, the Kardashian and Jenner clan were seen shopping on the Caribbean island. Kim, who is pregnant with her second child, reportedly wore a body-hugging black dress with a plunging neckline. Her younger sister Khloe Kardashian was seen in a similar black dress, albeit with a side cut.
