North West and Penelope Disick are the cutest "little mermaids" ever!
Kim and Kourtney Kardashian's daughters got all dressed up to meet a real-life mermaid during the family's St. Barts vacation on Tuesday. Well, Kim seems to think the mermaid is "real."

The cute cousins met the lady of the sea at the pool when she swam up to shore to chat. North was dressed as a green mermaid, while Penelope was a pink one.
The tiny tots seem to be having as good of a time as the older Kardashian-Jenner gals are in St. Barts. Aunt Khloe Kardashian snapped a pic of North earlier this week that was beyond adorable.
"MOOD," Khloe simply captioned the pic of her niece wearing crooked, over-sized sunglasses.

Kim has admitted that North is a "girly girl," and that was clear when she met the mermaid.
"Every day she wakes up and says 'shoes.' You have to bargain with her -- before you change her diaper she needs a pair of shoes on," the pregnant reality star told Vogue earlier this year. "North does love handbags, and anything where there's a little bit of glitz."
