Justin Bieber Responds To Black Keys' Drummer's Diss

Justin Bieber responded to the Black Keys' drummer's diss in a tweet, suggesting Patrick Carney be "slapped around."

"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," he tweeted to his 91,000 followers, and later responded to Bieber's tweet with a sad face.
