Scott Disick Joins Ex Kourtney Kardashian on Family Vacay to Costa Rica

It's a Costa Rican Kardashian vacay -- plus Scott Disick!
The father of three has joined his ex-girlfriend, Kourtney Kardashian, on the family's tropical trip. 
Kourtney and Scott aren't together anymore, but they're still close. Scott has shared a few pics of his ex since their split, including last Friday, when he posted a sweet Instagram snap of the brunette beauty tending to their 2-year-old son, Reign, on a helicopter. 
"Mom," he captioned the cute shot.

Kylie Jenner, Khloe Kardashian and Kim Kardashian are also on the family getaway, as are Kim's kids, 3-year-old North and 1-year-old Saint.
"Uncle Scott," Kourtney captioned a Snapchat of Nori cuddling up to Scott. 

Scott is definitely still part of the family. In fact, Kardashian matriarch Kris Jenner recently opened up about Scott and Kourtney's relationship during a radio interview on the Kyle and Jackie O Show.
"We knew Scott when he was 20 years old. He was a very young man, he was a baby! He was younger than Kendall is now for goodness sake," Kris shared. "They started a relationship very young and had three beautiful children. His parents both died in the same year a few years ago. He's been through a lot."
"I think he's had a bit of a challenging time," she added. "He's one of my kids, what can I say?"
