They always look like they're having a ball. And the Kardashian clan was at it again yesterday night as they threw a big bash to celebrate Kourtney's 39th birthday.

Of course Kim, 37, diligently recorded the night's epic proceedings on Instagram. Her story began with Kris, 62, standing and addressing the crowd while drinking and smoking a cigarette.

It seems Kim made up with her former assistant Stephanie Sheppard, as she shows up next in the story, and was apparently looking to cuddle up with her former employer.

Kendall, 22, gets in on the action as well, as she poses up a storm with her half sister.

Kim then shares a glimpse of her flattering outfit, which consisted of a tight, white strapless top and a form-fitting pencil skirt.

At the end of a quick walk, she then asks 'do you want to go to Dave Chappelle or the studio' before husband Kanye enters the frame.

While the rapper seems to not respond, the couple does end up locking lips for a sizzling smooch (our best part of the party).

Kourtney is then presented with a cake, and she proceeds to successfully blow out all the candles before taking some selfies with Kim.
