Kourtney Kardashian celebrated her 36 birthday Saturday night in Vegas with boyfriend Scott Disick ... and he looks less than enthused.
The bash was thrown at 1OAK. There was a pretty big crowd, sans all the other Kardashians. Kim's at home in L.A., Kylie's at Coachella with Tyga and Kendall.
Khloe was busy Saturday night throwing a shindig for her new group messaging app called Regroupd.
There was a buzz that Rob Kardashian might have gone to Coachella as well, but there's no evidence of it.
