A bunch of Kourtney's friends also shared some of their best memories of her:
No expense was spared for the swanky shindig ... the Don Julio 1942 bottles were flowing as were the inside jokes inscribed on napkins. If you're a huge fan of "Keeping up with the Kardashians," you know what's up. But, here's what takes the cake ... the damn cake itself!!! It's a massive desert showing off Kourtney's very own cakes.
Robin Thicke and Sia sang Kourtney "Happy Birthday" and a great time was had by all.
