Stars stepped out in full glamor and costume to celebrate the holiday at the Chateau Marmont on Saturday
Celebrities stepped out in full costume in Los Angeles as they attended Kendall Jenner’s Halloween party.
Eilish, 21, was decked out with a red wig, cowboy hat and faux shotgun as she arrived at the party with her friend Devon Lee Carlson. The "What Was I Made For?" singer wore a blue-and-white gingham blouse, a classic Western belt and a pair of brown trousers as she channeled the wild, wild West for the bash.
Tatum, 43, and Kravitz, 34, recreated Roman Polanksi’s 1968 thriller Rosemary’s Baby with the Magic Mike actor dressed in a light blue onesie with a bonnet and his girlfriend in a long white nightgown with a knife reminiscent of Mia Farrow’s titular character.
Megan Fox and Machine Gun Kelly stepped out in their usual all-out couples costume style, with the “bloody valentine” singer in full-face makeup, a black wig and black feathers and an all-black outfit, while Fox, 37, wore a mini schoolgirl skirt, blazer, white collared shirt and red tie while she carried a notebook that said “Death Note,” the film for which they based their costumes.
Natalia Bryant was also in attendance at Jenner’s get-together, and the late Lakers player’s oldest daughter dressed in an all-white ballet outfit a lá Black Swan. Bryant, 20, wore a full tutu and a feather headpiece in her hair as she recreated Natalie Portman’s character from the Oscar-winning film.
The King of Rock and Roll arrived, too, with Patrick Schwarzenegger dressed in a white jumpsuit with a bedazzled eagle on his chest and a peek of chest showing underneath. Schwarzenegger, 30, posed with his hands in a peace sign and a pair of white sunglasses as he arrived at the star-studded bash, where he was joined by his girlfriend Abby Champion.
Jenner's bash on Saturday doubled as date night for Charli D'Amelio and Landon Barker, who attended the party together as the infamous star-crossed lovers, Romeo and Juliet. D'Amelio, 19, wore an all-white ensemble with a pair of high block heels and white wings, while Barker, 20, wore an outfit reminiscent of a knight, with a mesh top and armor on his shoulders.
