Kourtney Kardashian isn't letting her relationship drama get in the way of some family fun!
The mother-of-three attended Kylie and Kendall Jenner's surprise graduation party on Thursday night, posing for pictures with her siblings at the special soiree.
In the pics, Kim, Khloe, Kendall and Kylie are hamming it up for the camera as Kourtney sports a huge grin in the photobooth.
"Graduating class of 2014 & 2015," Mrs. Kanye West captioned the family photo. "Congrats @kendalljenner & @kyliejenner for graduating high school! #SurpriseGraduationParty!"
Before the party, Kourtney reunited with ex-boyfriend Scott Disick to take their kids -- Mason, 5, Penelope, 3, and Reign, 7 months -- to lunch in Beverly Hills.
According to TMZ, the estranged couple drove separate cars to Scott's home in the Hollywood hills where she handed off the kids so he could spend time with them. Disick was later spotted grabbing dinner at Mr. Chow, while Kourtney celebrated with her family.
At least they're keeping things civil for the children, right?
As for the party, it looked like one helluva time -- with twerking, celeb attendees and even some killer gifts. Jenner revealed a few of her pricey presents on Snapchat, including one we're pretty sure came from boyfriend Tyga.
The rapper was spotted leaving Polacheck's Jewelers earlier in the day -- a store specializing in fine jewelry and fancy watches. Kylie's presents: A diamond-studded Rolex and Cartier nail bracelet. The store wouldn't comment on his purchases, but you do the math.
