THE Casamigos Halloween party — the annual bash hosted by George Clooney and Cindy Crawford's husband Rande Gerber's tequila brand — has drawn celebrities in out-there outfits.

Crawford and Gerber, their teenage children Kaia and Presley, Zoe Kravitz, Harry Styles, Olivia Munn, Paris and Nicky Hilton and Dave Grohl were among the stars who came out for the party in Beverly Hills as the Halloween weekend kicks off.

Crawford dressed up as Blondie singer Debbie Harry, while her look-alike daughter Kaia, 17, went as Joan Jett. Husband Rande stuck with the musician theme, dressing up as David Bowie.

Harry Styles was in attendance, dressing up in a glittering Elton John look. Olivia Munn was also there dressed as Peik Lin from Crazy Rich Asians.

It was unclear who Big Little Lies star Zoe Kravitz was meant to be. The actress wore a dressing gown and Seinfeld socks, fake blood and vampire teeth, and carried a newspaper.
