These guys stick together.

Nearly two weeks after announcing exclusively to PEOPLE he and Jennifer Meyer were ending their marriage, Tobey Maguire stepped out Friday for a guys’ night with his longtime friend Leonardo DiCaprio at Casamigos’ annual Halloween party (hosted by Rande Gerber, George Clooney and Mike Meldman) in Beverly Hills, California.

Making a low-key arrival around 10 p.m., the star stayed incognito in a blue monkey mask and roamed through the party before meeting up with the Oscar winner after he arrived just before midnight with an entourage.

“They were drinking Casamigos cocktails, having a blast and super upbeat,” says a fellow partygoer about Maguire and DiCaprio. “At the end of the night, Leo was dancing like crazy with Robin Thicke. They were cracking up the other guests.”

Thicke and his girlfriend April Love Geary were dressed as the title characters from Pretty Woman and also broke it down on the dance floor.

At the end of the night, Thicke got onto the mic and addressed the crowd, saying “Let’s get the party started … it’s here on the dance floor. Let’s get the cops called!”

Two minutes later, the “Blurred Lines” singer got his wish and the party was shut down by police.

Other famous faces at the party included hosts Rande Gerber and Cindy Crawford (dressed along with their kids Kaia and Presley as the Sex Pistols), Hilary Duff and her new boyfriend Jason Walsh (the couple matched in a pilgrim and Native American chief costume), Nina Dobrev (dressed as the bear from DiCaprio’s The Revenant), Sascha Baron Cohen and Isla Fisher and James Corden and his wife.
