Black Keys drummer Patrick Carney was followed to his cars after his triumphant win at the Grammys, where a TMZ camera man asked about Justin Bieber's Grammy snub, to which he responded "He's rich, right? ... Grammys are for music, not for money ... and he's making a lot of money." Now, Patrick is facing a backlash by Justin Bieber fans, and now Bieber himself is chiming in.

The teen popstar chimed in on Patrick's comments, saying "the black keys drummer should be slapped around hahah [sic]."

Patrick retweeted Justin's message with a frown emoticon, and had earlier tweeted "It's cool when you get cornered outside your hotel by a guy with a camera and they ask you a dumb question and then put it on TV. :("
