Casamigos brought its annual starry Halloween party back to co-founder Mike Meldman’s LA home this year — with guests including Justin Timberlake (dressed as a microphone) and Jessica Biel (dressed as Timberlake, complete with pals dressed up as his old boy band NSYNC).

Meldman’s house had a psychedelic theme, with neon galore and graffiti. His Casamigos partner Rande Gerber and supermodel wife Cindy Crawford were decked out in swinging ‘60s gear, while Nina Dobrev dressed as Billie Eilish and Lisa Rinna was JLo in her iconic Versace dress.

Also at the bash: Gerard Butler, Laverne Cox, Paris Hilton, Billy Bush, Brian Grazer, and Dave Grohl.
