Given the music provided on the event, Scott could deem his banishment a blessing in disguise.
Kourtney flew from The Hamptons, where she is filming the E! spin-off show, to their home in Calabasas, California to host her niece's first birthday party with sister Kimmy.
A source told TMZ Kourtney decided not to let Scott attend ('cause he's been acting like he always acts) but her actions backfired when he opted to stay in Southampton, New York to enjoy a (very) belated birthday celebration for himself on Saturday, after turning 31 on May 26th.
TMZ reports: "Disick didn't stew over the snub - he had a belated birthday party at 1Oak [club] in The Hamptons where he sprayed champagne on fellow party-goers."
The source claims Kourtney believed Scott would "feel the burn" for being left out because North's party was thrown in their backyard: "The tension revolves around Scott's propensity for partying and leaving the family in the dust. Kourtney gave Scott's plane ticket to a nanny... again, a not-so-subtle insult that seemed lost on Scott."
Scott, who has children, Mason, four, and Penelope, 23 months, with pregnant Kourtney, reportedly arrived at 1Oak in his Bentley with a huge entourage in tow shortly after midnight and wasted no time letting his hair down.
Party-goers claim he was 'pretty wasted' and didn't seem to mind being away from his girlfriend one little bit.
Of course, you can see all the "drama" when the episode airs on that Hamptons aforementioned spin-off jobby.
