Scott Disick Parties In Vegas & Leaves Kourtney Kardashian At Home

Scott was having a blast at the hot 1-Oak night club, and he was throwing dollar bills all over the place! Meanwhile, Kourtney was home with Mason and Penelope.
Scott Disick doesn't act like a father-of-two! The reality star was partying like a single kid on spring break as he hit the club for a Halloween party in Sin City.

Scott was the spitting image of Patrick Bateman from the cult classic American Psycho. But for a guy that gets such heat for being too wild, it's shocking to see him out without Kourtney Kardashian.

Meanwhile, Kim Kardashian hit up NYC hotspot Avenue with Kanye West and camera crews in tow.

Do you think Kourtney should be upset with Scott?
