The 37-year-old reality star and 33-year-old club promoter looked the happy couple in new Instagram photos as they rang in the new year with their three children.
Kardashian and Disick shared posts Monday of themselves dancing and posing on a private plane. The reality star captioned her gif "Disco disco @letthelordbewithyou," while Disick wrote, "Fly or die type."
The Keeping Up with the Kardashians star previously shared a picture of herself and Disick cuddled up on the ski lift. The couple's children Penelope and Reign also appeared in other snapshots.
Kardashian and Disick recently reconciled after splitting in 2015 after nine years of dating. Hollywood Life reported over the weekend that the pair are "stronger and healthier as a couple than ever before."
"Kourtney is doing her part. She has a lot of strong feelings for Scott and she is enjoying having him around," a source said. "She sees how much happier their children are when he's around, so she is being patient with Scott and trying to be forgiving of his rocky past."
"They have been laughing a lot and enjoying each other's company. Kourtney and Scott have taken the kids to Aspen for some skiing and are continuing to get along great," the insider added.
Sources told Us Weekly in November that Kardashian and Disick were living together again and seeing "what happens" over the holidays. The couple share 7-year-old son Mason, 4-year-old daughter Penelope and 2-year-old son Reign.
