The "Keeping Up with the Kardashian" star, 37, noticeably left Scott's name off of her festive family gingerbread house, which she shared on Snapchat on Thursday, Dec. 1, 2016.
Kourtney and her three kiddos, Mason, 6, Penelope, 4, and Reign, 1, all got nameplates on the roof of the grand snow-covered candy mansion.
"Scott's mellowed out a lot and hasn't been partying," the insider explained of the 33-year-old, who has been in and out of rehab in the past.
Sources at Us Weekly even claimed that he's been staying with the family at Kourt's home in Calabasas, California.
Not to mention, they were spotted together in Mexico back in November, on vacation without their children.
Hey, maybe there just wasn't any room left on the roof?
