Bieber rips Carney: Black Keys drummer needs to get 'slapped around'

Justin Bieber walked away from the Grammy Awards empty handed this year. In fact, he wasn't even nominated.

The Black Keys, on the other hand, took home four of the gramophone trophies in Sunday's ceremony, and drummer Patrick Carney took the opportunity to gloat a bit.

"He's rich, right?" Carney said Sunday night, when asked after the ceremony if Bieber should feel snubbed. "Grammys are for like music, not for money, and he's making a lot of money. He should be happy."

Ouch!

The Biebz apparently isn't too pleased with Carney's comments, tweeting Tuesday morning that Carney "should be slapped around."

the black keys drummer should be slapped around haha
