The 37-year-old reality star and 33-year-old club promoter treated their three children, 6-year-old Mason, 4-year-old Penelope and 23-month-old Reign, to a day of sledding amid rumors of their reconciliation.
Kardashian shared a photo Monday on Instagram of herself carrying Reign back up the hill. Disick later posted a picture of himself holding Reign while sledding with Mason and Penelope, writing, "Fast times."
Kardashian and Disick were all smiles when they were spotted grabbing coffee together the same day. The couple split in July 2015 after nine years of dating, but E! News reported last week that the pair are back together.
"They are back together and giving their relationship a try again," a source said. "Scott's mellowed out a lot and hasn't been partying."
According to a previous report from Us Weekly, Kardashian and Disick are living together again and seeing "what happens" over the holidays. Disick has reportedly been staying at Kardashian's home "the last few weeks."
"He has really cleaned up his act and been well-behaved. Kourtney is always skeptical about how long it will last, but she has been very encouraged to see how much he has been trying," an insider said.
"They are planning to do everything together over the holidays with the kids and will see what happens," the source added. "For now, they are taking little steps in the right direction."
