In November, PEOPLE reported that the duo, who ended their nine-year relationship last July, are getting along great and are now living together again.

“For a long time, it really seemed like Kourtney was completely over Scott. She was acting very disappointed. It seemed she would never take him back. Then Scott decided to turn things around,” a source said of Disick’s decision to change his behavior. “It was like he finally realized that he needed his family. For the past few months, Scott has been amazing. He isn’t sober, but very well behaved. He has shown Kourtney that she and the kids are his number one priority.”
