Turns out St. Barts is where dreams come true! North West and cousin Penelope Disick just met a real-life mermaid, and mom Kim Kardashian's Instagram photo is almost too cute for words.

In case you missed it (yeah, right!) the reality TV family are currently vacationing on the Caribbean island, and have already been photographed shopping, going on a boat trip, and generally enjoying themselves in an array of barely there outfits.

But on Tuesday, Aug. 18, it was 2-year-old Nori and her 3-year-old cousin Disick who stole the show. Dressed in super-cute matching mermaid outfits themselves, the toddlers stood mesmerized as a real-life mermaid poked her head out of the pool, her face covered in glitter, her neck adorned with a pretty shell necklace, flapping her big pink tail in the air.

Mermaids are real ????

"Little mermaids," excited mom Kardashian, 34, captioned the snap, also sharing a photo of the mermaid in action, taking an underwater swim in the shallows of the pool. "Mermaids are real," Kardashian added.

Earlier in the day, little West was looking altogether more grown up in a hilarious snap shared by aunt Khloe Kardashian which showed the little tot partying hard, holding an iced drink, while her adult-sized sunglasses fell off her nose.

The entire exotic family vacation is being filmed for the clan's hit TV show, Keeping Up With the Kardashians.
