Kylie Jenner, Kim and Khloe Kardashian Attend Diddy's 50th Birthday

We only party if we shimmer. That’s what we suspect the Kar-Jenner babes said before heading out to attend Diddy‘s epic 50th birthday party on December 14. Kylie Jenner and big sis Khloé Kardashian arrived with their glitz and glamour at an all-time high, rocking the most sparkling looks we’ve seen from them to date.

The 22-year-old took several snaps of herself and her sister, 35, while en route to the lavish party, calling the outing a “date night” for them on both her Instagram feed and Stories. Khlo also showed off “a tease” of her bejeweled jumpsuit on her IG Stories, shouting out her stylist Dani Michelle.

Believe it or not, Kim Kardashian and husband Kanye West were also in attendance for the milestone moment — and the rapper even reunited with Jay-Z. It’s been three years since the duo fell out with one another so, needless to say, it made the party an even bigger moment than it already was.

An insider told Us Weekly that Kim, 39, Kanye, 40, Jay, 50 and wife Beyoncé spent time together in the VIP section of the party, held at Diddy’s Los Angeles home. “They greeted each other and seemed friendly and happy to see each other. The Carters and the Wests were all in a section behind Diddy and his family,” the source explained. They also noted that KUWTK mama Kris Jenner and close pal Jonathan Cheban were also part of the crew.

The eyewitness also confirmed that Ky and Koko stayed together for most of the evening. Plus, the makeup mogul‘s two most famous exes, Travis Scott and Tyga, both also made appearances at the star-studded event … but didn’t interact with each other. Neither did Kylie and her 30-year-old ex. Needless to say, the joint was jumping and full of friends and familiar faces.

Seems like it was a pretty great party! Scroll through the gallery to see photos of the Kar-Jenner sisters at Diddy’s 50th birthday bash.
