Casamigos held their annual ‘Brought to You by Those Who Drink It’ Halloween party on Friday (October 27), at a private residence in the heart of Beverly Hills, where invite-only guests were welcomed into a surreal parallel universe. 

There were many standout looks and moments from the evening.

Paris Hilton dressed as her BFF, Britney Spears, as the ‘Toxic’ stewardess.

Also honouring the princess of pop’s biggest hits, was Kelly Sawyer Patricof who channelled ‘…Baby One More Time’ Britney, while her BFF Jessica Alba was also in Britney Spears’ Toxic’ mode wearing a diamond-studded bodysuit.

‘Kill Bill’ inspired Megan Fox and Machine Gun Kelly’s looks channelled Beatrix Kiddo and Gogo Yubari, following their Tommy Lee and Pamela Anderson looks from last year.

Also sporting a schoolgirl look, was actress Jodie Turner-Smith, who partied with actress Nancy Gomez.

I’m kinda surprised by Jodie’s lack of creativity here.

Rande Gerber and Cindy Crawford donned ‘Grease’ cast outfits as Sandy and Danny.

Kaia Gerber sported a short blonde wig as Edie Sedgwick, whilst beau Austin Butler channelled his inner Andy Warhol.

Wait? What? Is this Alessandra Ambrosio channeling her inner Victoria’s Secret model for a Halloween Party?

Justin Bieber attended as a scuba diver with flippers, leading the dancing in front of the DJ booth singing ‘Despacito.’

Victoria Justice turns back time as Cher.

Chord Overstreet sported an Old Spice jumpsuit with his BFF Glen Powell in Wonder Bread jumpsuit.

Did you get the film reference?

The were channelling Cal Naughton, Jr. (John C. Reilly) and Ricky Bobby (Will Ferrell) from the 2006 film ‘Talladega Nights: The Ballad of Ricky Bobby.’

Margot Robbie arrived in head-to-toe in black wearing a Guy Fawkes mask, more recently known as the V for Vendetta Mask.
