Kendall and Kylie Jenner Party With Friends at Justin Bieber and Hailey Baldwin's Wedding

Justin Bieber and Hailey Baldwin just married (for the second time!) on Monday, Sept. 30. We know this because the event was full of party favors, from t-shirts to personalized champagne bottles, with the special date date popping up everywhere. And of course, this was all shared on social media.

Their wedding, which was held in South Carolina at the luxurious Montage Palmetto Bluff, was full of very famous friends of the couple, including Kendall and Kylie Jenner.

Kendall posted a picture on Instagram prior to the wedding with her not-date date, BFF Fai.

Kylie wore the most insane gold dress and slipped in a pic on Instagram of her kissing her daughter, Stormi, who was wearing a pink tutu dress and also attended the A-list event.

The party was absolutely packed with glamorous and beautiful people, as Kendall graciously reminded us with her numerous posts.

But the guests weren't the only glammed up people there, of course. Hailey and Justin took some bridal photos together in their wedding photobooth and they looked just so adorable.

Kendall was very involved with pre-wedding festivities. She helped plan Hailey's bachelorette party, complete with a stop at a sex store where she grabbed accessories for the bash. The group then had dinner as Ysabel and partied at Delilah in Los Angeles.

While Hailey and Justin got married in a courthouse in New York City last year, they finally had an official wedding ceremony with family and friends, and it looked like it was as lovely as the couple deserved.
