Justin Bieber

Justin Bieber is biting back after Patrick Carney, the drummer for the Black Keys, essentially said the Biebs doesn't deserve a Grammy.

After Bieber, a two-time nominee, did not even receive a Grammy nomination this year, Carney joked to TMZ.com after Sunday's awards, "He's rich, right? Grammys are for music, not for money... and he's making a lot of money."

Bieber, who hosted Saturday Night Live the night before the Grammys, did take too kindly to the insult. "The Black Keys drummer should be slapped around haha," Bieber tweeted.
