Kendall Jenner is kicking off her birthday celebrations!

While the supermodel doesn't officially turn 24 until Nov. 3, she decided to get the party started a few days early. On Thursday night, Kendall hosted a star-studded Halloween birthday celebration at Blind Dragon in West Hollywood. Kourtney Kardashian, Gigi Hadid, Bella Hadid, Caitlyn Jenner, Hailey Bieber, Jaden Smith and Kaia Gerber were among the celebs in attendance at the bash, celebrating alongside the birthday girl. Kendall's brother, Rob Kardashian, was also spotted at the party in honor of his sister.

"Everyone came dressed in costume and went all out with makeup and props," a source tells E! News. "There was dancing all night and a photo booth. The club looked amazing with glowing jack o' lanterns hanging from the ceiling and big cobwebs to walk through."

For her birthday party, Kendall appeared to dress as a fairy, showing off her golden wings on social media. The Hadids also turned heads with their costumes, with Gigi dressing up as Jim Carrey's character from The Mask, while Bella channeled Catwoman. Kacey Musgraves also attended the Keeping Up With the Kardashians star's party, dressed as a Dallas Cowboys cheerleader.

"There was a costume contest and they gave out trophies for different categories," the insider continues. "Kendall judged the costume contest and got on the microphone to announce the winners. One of the funny prizes was dinner and a movie with Fai Khadra."

"Kendall had an amazing time and was running around dancing and talking with all her friends," the source shares with E! News. "She loved checking out people's costumes and got a kick out of how creative people were."

The insider adds, "When the party died down late night she went to Drake's after-party at Delilah."

Other guests at Kendall's party included Leonardo DiCaprio, Emily Ratajkowski and The Weeknd, who was dressed up as the Joker.

According to a second source, "Bella Hadid and The Weeknd arrived together and were together all night. They looked amazing in their matching costumes. They were seen having several drinks together and took photos together in the photo booth."

"It definitely seemed like they were back together," the insider says, adding that Bella was "hanging on" the Grammy winner's shoulder "for a while" and that "they were together majority of the night."

The source also shares that Leonardo came without girlfriend Camila Morrone and that the actor was wearing a mask.

"He said hello to Kendall and was chilling at a booth with a few guy friends while having a drink," the insider tells E! News.
