Kendall Jenner turned 25 in November, celebrating with a Halloween-themed birthday party somewhere in California. It was a large-scale and celebrity-filled event. A-list stars like Justin and Hailey Bieber, Doja Cat, The Weeknd, and assorted members of the Kardashian-Jenner clan attended the birthday bash. Many of the attendees boldly posted photos from the party on their social media, showing off their maskless faces and physical closeness.
