Kardashians Throw the Party to End All Parties for Kourtney’s 40th

Kourtney Kardashian had a 40th birthday party to remember!

The ultimate Kardashian bash included the famous family, their A-list friends, Kourt’s exes, an NSFW cake and Robin Thicke serenading the birthday girl!

Kourtney stunned in a sheer-paneled LBD by Versace, while sister Kim showed off her figure in an embellished couture dress by the famed designer.

Khloé was decked out in Swarovski crystals that cost $65,000! Kylie was turning heads in a sparkling gold crop top and matching skirt. Meanwhile, Kendall wore a floor-length gown with a sexy slit up the side, and mom Kris showed off her stems in a black minidress by Dolce & Gabbana.

Other famous faces included Kanye West, Travis Scott, and Paris Hilton… and two of Kourtney’s exes, Scott Disick and Younes Bendjima.

The ex-boyfriend making the most waves, however, was Khloé’s former beau French Montana. His presence only fueled rumors that they could be getting back together.

The K-Bash also included a cake molded to look like the birthday girl in her birthday suit, personalized $200 Don Julio 1942 tequila bottles with Kourtney’s face etched on the side, and performances by Thicke and also Sia… without her famous wig.
