Kourtney Kardashian must have been feeling nostalgic as she posted a sweet snap from her recent Costa Rica vacation to Instagram on Friday.

The natural stunner, 40, shared an adorable photo of herself with niece North, six, and daughter Penelope, six, on a yacht from their family getaway last week.

Kourtney pulled down her sunglasses for the pic as cousins North and Penelope posed with their retro shades on while leaning on the luxury ship.
The Kardashian-Jenner clan were staying at Villa Manzu, which boasts eight suites, on the Papagayo Peninsula.

Kourtney was on the trip with her kids and ex-partner Scott Disick, as well as sister Kim, 38 and her husband Kanye West and their daughter North.

Kourtney and Scott, 36, share three children, Mason, nine, Penelope, six, and Reign, four.
