George Clooney and Rande Gerber may have pocketed a billion bucks when they sold Casamigos, but they're still involved in the traditions of the company -- namely, the always epic Casamigos Halloween party.
They threw a '70s-themed bash at Tower Records in WeHo, and tons of stars showed, including Kim Kardashian, David Spade, Courtney Love, Chuck Liddell, John Hamm, Russell Simmons, Seth McFarlane, Adam Levine, DeAndre Jordan, Steve Tisch, and on and on.
