Kourtney Kardashian Shares New Year's Kiss With Reign as Scott Disick Parties in Las Vegas

New year, not-so-new Kourtney Kardashian and Scott Disick.
While the estranged couple seemed inseparableover the Thanksgiving holiday, Kourtney and Scott reined in the New Year in very different ways. 
Scott appeared at 1 Oak Nightclub in Las Vegas, marking his first post-rehab club appearance. Despite being photographed surrounded by scantily clad dancers, the 32-year-old reality star was on his best behavior.

Clad in a Tom Ford suit, a source tells ET that Scott sipped water all night and seemed “very happy and positive,” surrounded by his friends.

Scott didn’t spend too much time in Sin City, either. Following an epic countdown to the New Year, Scott hopped a private jet back to Los Angeles. "Happy new year! LA, I'm coming home,” he captioned the Instagram pic.
Meanwhile, back at her house, Kourtney, 36, celebrated the end of a difficult year with her close friends and family, playing Cards Against Humanity.
And her big kiss for the New Year? Her one-year-old son, Reign, had the honor.

Prior to New Year’s Eve, Kourtney revealed her resolutions for 2016 on her app. Among them, she wants to "live more in the present and less on my phone" and "refocus my priorities, making sure that ‘me’ is high on the list (children, God, me, family above all else…)." And of course, she also plans, "to continue on the workout mission that [she] started this year," the results of which have been impressive.
The estranged couple ended their nine-year relationship after Scott was spotted on vacation with an ex-girlfriend in July. Scott subsequently checked into rehab in Malibu, where he stayed for a month. 
Watch Scott tearfully attempt to apologize to Kourtney, Kim, Khloe and Kris after those photos of him with other women surfaced in the video below.
