Gerard Butler, Josh Hartnett, Shaun White, Rose McGowan and a host of Hollywood hipsters blew off steam over Oscars weekend at Chez André, the karaoke club with a live band that popped up at the Standard, Hollywood. Chris Stills, son of Crosby, Stills, Nash & Young’s Stephen, performed “Ohio” by his dad’s band. Also at Andre Balazs and André Saraiva’s club (where one guest sang in a tube sock and top hat) was DJ duo Daft Punk, “Shame” director Steve McQueen, and former porn princess Sasha Grey.
