According to E! News, Disick rang in the new year in Las Vegas at 1OAK nightclub, where he is known to frequent.
1OAK shared a photo of Disick counting down to 2016 at the nightclub and looking like he was having a blast.
WARNING: There is some strong language in the video below.
And while Disick doesn't appear to have a drink in hand, it still isn't recommended that someone who so recently spent time in rehab for addiction problems be so close to so much alcohol.
Meanwhile, Disick's ex, Kourtney Kardashian, shared her sweet New Year's Eve kiss on Instagram.
It looks like the mom of three spent her time at home with her kids, planting a cute peck on little Reign.
What makes Disick's partying ways even sadder is that a recent Keeping Up With the Kardashian's clip showed Disick crying with remorse over the way he treated Kourtney and the rest of the Kardashian/Jenner clan.
Disick seemed like he was really trying to make amends for cheating on Kourtney, and he alluded to the fact that he wanted to help himself so that he could help Kourtney and the kids.
A nightclub in Vegas just doesn't seem like the place for a recovering addict to get the help he needs. Although it is important to note Page Six reports that Disick did stay sober throughout his NYE hosting duties.
