We have an inside look at Hollywood’s most star-studded Halloween Party this year, which had a Severance theme and was hosted by Vas J Morgan and Michael Braun.

Ashley Benson, Paris Hilton, Ryan Phillippe, Camila Cabello, and Emma Roberts were among the attendees at the event on Friday night (October 31) at a private residence in Los Angeles.

More attendees included Lily Allen, Orlando Bloom, Joey King, Logan Lerman, Tiffany Haddish, Camila Cabello, Kiernan Shipka, Paris Jackson, Kaia Gerber, Chace Crawford, Bebe Rexha, and so many more.

The party was supported by Jas Mathur‘s Limitless and Lucy Guo‘s Passes. Guests snacked on Raising Cane’s chicken fingers courtesy of founder Todd Graves. Cocktails were provided by Melquiades Tequila.

A replica of the Severance set was built for the party, with guests encouraged to sever themselves upon arrival at the party.

“Your ‘outie’ has responsibilities of work and life that the party allows you sever yourself from (same as Lumen Corp. does for the characters in the show). Your ‘innie’ exists only to have fun and dance within the party,” Vas J Morgan said of the concept.
