Wow! This is SERIOUS co-parenting goals!

A fan snapped some shots of Kourtney Kardashian sitting at a dinner table with Scott Disick and his much-younger girlfriend Sofia Richie in Cabo San Lucas, Mexico as the awkward trio vacationed with Kourt and Scott's kids Mason, Penelope and Reign south of the border.

Fans took the Twitter to commend the former couple for being such adults and Khloe chimed in! #ItsAKardashianChristmas!
