She was spotted ringing in younger sister Khloe’s birthday the night before.

But 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.

Not on the family trip however, was Scott’s 20-year-old girlfriend Sofia Richie, who sometimes comes with the former couple on their family getaways.

Kourtney and Scott were seen laughing together during a beach outing in the week as it seems they’re getting along great these days.

The duo split in 2015 after nine years together and lots of drama mainly surrounding Scott’s issue with substance abuse.

There were rumors earlier this month that Scott and Sofia were talking about getting engaged.

A source told UsWeekly: ‘[Kourtney is] not only unbothered by the idea of them getting engaged, they’d [even] have her full support,’

In an earlier People report a source revealed: ‘As much as people would love there to be, there isn’t any drama between Scott, Sofia and Kourtney,

‘They spend a ton of time together, and Kourtney is comfortable with Sofia around the kids.’
