PHOTOS: The Best Costumes From Inside One Of Hollywood's Biggest Halloween Parties

One of Hollywood's biggest Halloween parties took place on Friday night, and the costumes are giving us some serious inspiration.

Casamigos co-founder Rande Gerber — husband to Cindy Crawford and father of Kaia Gerber — hosted his annual Casamigos Halloween bash at a private home in Beverly Hills, Los Angeles and from Paris Hilton to Megan Fox, the A-listers who attended clearly pulled out all the stops.

Unfortunately, it doesn't look like Gerber's close friend and Casamigos partner George Clooney attended the event.

Clooney and Gerber started the tequila company Casamigos, which means "house of friends", in 2013. The idea came to them during a trip to Mexico where they drank a lot of tequila and decided to start their own company, according to Insider.

The business partners sold the company to Diageo in 2017 for $1 billion.

Every year they get together to throw an epic Halloween bash with a star-studded guest list, and according to the photos Casamigos sent to Narcity, this year's event didn't disappoint.

From Paris Hilton dressed as Sailor Moon to Brody Jenner sporting a Dr. Anthony Fauci costume, here's who attended and what they wore.
