Kendall Jenner’s annual Halloween party was a star-studded event, featuring top guests like Charli XCX, Troye Sivan, Rosalía, and Addison Rae. The group posted a TikTok enjoying Addison’s new single, “Aquamarine,” which has gained a huge following since its release. Charli attended as a character from the horror series Masters of Horror, while Troye dressed humorously as Addison, specifically recreating her viral pap walk with Britney Spears’ memoir in hand.

Alongside them, Megan Fox and Machine Gun Kelly joined the festivities, as did Camila Cabello. Kendall, in her usual fashion, showcased two looks: one with her sister Kylie as Lizzie and Isabella from Lizzie McGuire, and an earlier costume as Paris Hilton from The Simple Life alongside Hailey Bieber, where they reenacted a scene involving Paris’ memorable comeback to being called “dumb and dumber.”

Paris Hilton herself gave a nod of approval, commenting on the TikTok with, “Icons recognize icons 💅🏼 Obsessed with this!” Overall, the event’s high-profile guest list and creative costumes set the tone for one of Hollywood’s most talked-about Halloween gatherings this season.
