Sofia Richie Calls Scott Disick This Sweet (and Delicious) Nickname and It’s So Cute

In the two years Scott Disick and Sofia Richie have been together, they’ve evolved into one of our favorite celebrity couples and they’ve only gotten cuter. The best couples always have the most adorable pet names and the 20-year-old model revealed her special nickname for her 36-year-old bae after his birthday party on May 26.

“Happy birthday muffin!” she wrote over a cute snap of the couple from the photo booth at his party the night before. “Best night!” What a sweet pet name for Scott, who (now that we know what Sof calls him) totally looks like a “muffin” to us.

The younger model even had a blast with Scott’s baby mama, Kourtney Kardashian, at the party, which proves things are really going strong for this family unit. They even cuddled up close, smiling for photo booth snapshots with the birthday boy and little Kar-Jenner sis, Kylie Jenner.

“Best night celebrating you, @letthelordbewithyou, 📌” Sofia captioned a selection of photobooth images on her Instagram feed, including one of the foursome. “An amazing soul. We all love you very much.”

This is hardly the first time Kourt, 40, and Sof have been in the same room, let alone actually hanging out together, but every time they do we’re reminded of their maturity. Scott and his baby mama may have ended things years ago, but the couple is dedicated to staying strong in their coparenting — needless to say, they’ve done an incredible job.

They’ve been honest about the fact that “new relationships” are difficult to overcome, but Sofia has also done her part in not rocking the boat and seems truly dedicated to finding her place in the fam. When they all come together for special events, it’s clear there is a level of mutual respect and love for all involved.

Happy birthday, indeed, muffin — we all love you, not just Sof.
