The Kardashians have once again proved that they know how to throw a party. Despite dealing with the strain of Lamar Odom's health issues,​ the famous sisters gathered together on Sunday to celebrate the upcoming birth of Kim Kardashian's second child. The theme of the party? The classic '80s flick Troop Beverly Hills.

Friends and family including Kris, Kendall, and Kylie Jenner as well as Khloé and Kourtney Kardashian and, of course, the guest of honor gathered together at the Azoff House in Beverly Hills, Calif. Just like the girls do in the Shelley Long film, the Kardashian-Jenner clan went camping in a hotel room, complete with small teepees and Troop Beverly Hills signs.

Kylie shared a snap of her and Kourtney being "wilderness girls" while having their morning coffee. "Just our usual morning routine #troopbeverlyhills #sipstea," she wrote in the caption:

The dress code was pajamas only—most of the ladies wore for blue striped sets while Khloé opted for pink to pair with her new lob haircut. Kris Jenner reportedly attended and made a heartfelt speech to her expectant daughter. Looks like a super fun party!
