Inside Kourtney Kardashian's Birthday Weekend!

The latest Kardashian-Jenner family party had a little bit of something for everyone. The family came together for Kourtney Kardashian's 36th birthday celebration at her and Scott Disick's home in Calabasas, CA, on Sunday. While Kendall and Kourtney shared a cute moment with Mason and Penelope Disick near the gorgeous birthday cake, Kylie Jenner stole the Instagram spotlight with her revealing bikini snap. The reality star filled up her feed with even more bikini snaps from her time at Coachella.

Kourtney's birthday weekend also included a trip to Las Vegas with Scott. Interestingly enough, Sunday's episode of Keeping Up With the Kardashians details Scott's bizarre behavior during a trip to Sin City for matriarch Kris Jenner's 59th birthday party in November. Still, it seems Kourtney and Scott have put the incident behind them following the birth of their third child, Reign Disick, in December. In a photo Scott posted from the flight home from Vegas this weekend, the long-term couple lounges while kicking up their feet on a private jet. "@kourtneykardash and I knocking boots last night," Scott wrote. Read on to see the family's latest snaps!
