Dave Grohl filled in for host Chelsea Handler last night on Chelsea Lately, where he led a panel discussion parsing the Grammys' snub of Justin Bieber, who wasn't nominated for any awards this year. "Is anyone really surprised?" the rocker quipped. "Honestly, he's dancing around so much, it's probably better his microphone isn't on because if it were, it'd just be like, 'UHHHUHHHH,'" he continued, mimicking a gasping sound. But Grohl doesn't have anything against the pop star, agreeing with the panel that Bieber has a certain appeal. "I like him, too. I think that if I were 18 or 19 years old and had $100 million, I would look exactly like that."
