Newly single Demi Lovato popped by Beacher's Madhouse at The Roosevelt Hotel in Hollywood Wednesday, grabbing a seat with pals Kim and Khloé Kardashian. The starlet was really into the stage shows, and sang along with the house auto-tune band, Pop Shop, as they played Nicki Minaj's hit "Superbass." The singer didn't seem to mind when ex Wilmer Valderrama arrived at the club, and looked on as the Kardashian sisters hit the stage when the DJ blasted the latest Jay-Z and Kanye West hits.
