They’re one big happy family! Sofia Richie may have a 20-year age gap with Kourtney Kardashian, but they don’t let that stop them from hanging out like besties. While celebrating Scott Disick‘s 36th birthday, the girlfriend and baby mama had the ‘best night’ with everyone, cuddling up close and smiling for photo booth snapshots with the birthday boy and their other pal, Kylie Jenner. On Sunday, May 26, the KUWTK stars gathered a whole crew of people for their celebrations, and it looks like it was a blast.

Best night celebrating you, @letthelordbewithyou, 📌” Sofia, 20, shared on Instagram on Monday, May 27. “An amazing soul. We all love you very much.” In the photos, the model snuggled up to her man, mean-mugged with him and his friends, and flashed a grin with Scott, Kourt, and Kylie. Though this is far from the first time that Scott’s ex and his current girlfriend have hung out, fans couldn’t help but be impressed with how chill they both were. “Your level of maturity is out of this world,” complimented one. “You are a very understanding girlfriend,” joked another. 

Of course, some fans had to have a little fun at their expense. “This feels so awkward,” wrote one commenter. Another teased, “[Scott and Kourtney] kinda look like Sophia and Kylie’s parents.” The stars’ have never let trolls get to them, though, and they certainly weren’t about to let anyone rain on Scott’s (metaphorical) birthday parade. Instead, they were too busy partying to worry about how their night looked to anyone else. And it seems like it paid off!

“Best birthday ever,” Scott commented on his Instagram Story, posting a photo booth pic of him with his daughter, Penelope. In another string of photos, he and Sofia got cozy as they made fierce faces for the camera. Kissing him on the cheek in the last shot, the 20-year-old had no qualms about showing off a little PDA at the party. The father-of-three even gave fans a sneak peek into the “after party” where P and Kylie were snuggling together on a couch by a warm fire.

Some fans may think the family’s arrangement is “awkward,” but we love how close they all still are. Scott and Kourtney may have called it quits years ago, but they’ve made an effort to keep their coparenting going strong, and they’ve done an incredible job. Though they’ve mentioned “new relationships” are the hardest part, Sofia has also done her best not to rock the boat and to find just where she fits in the fam. When they all get together for special occasions like this one, it’s clear just how much love there is for everyone — and we’ve got love for them all, too.
