Chris Brown just got a little less popular. Singers including Pink and Joe Jonas are lambasting him for lip-syncing "Turn Up the Music," the song he performed at the Billboard Music Awards program. "One day if I lip-sync, I hope I do it as well as him," snorted Pink in a tweet. Husband Carey Hart chimed in: "I'm pretty sure I saw my wife do that same performance, but she was 3 months pregnant and actually sang the song." Asked Jonas: "What ever happened to people singing live???" Brown, who apparently doesn't know and doesn't care, is—still—keeping quiet.
