It’s on between Patrick Carney and Bieber

Justin Bieber’s getting a bit feisty in his old age, ripping Patrick Carney on Tuesday after the Black Keys drummer told photogs on Sunday night that the Biebs didn’t deserve a Grammy.

“Grammys are for, like, music, not for money ... and he’s making a lot of money,” Carney told TMZ after being asked how he felt about Bieber’s Grammy-nomination snub.

“He should be happy.” That didn’t exactly make the younger musician happy. “the black keys drummer should be slapped around haha,” Bieber tweeted Tuesday. As of mid-afternoon, his wish had been retweeted by fans more than 36,000 times. Bieber’s had a lot to make him cranky on Grammy Sunday, when he tried to live-stream online counterprogramming of himself against the awards show, only to be thwarted by a blast of Bieber Fever shutting down the streaming service twice. “since nothing is working and im super upset i feel i gotta make it up to u. i should post a new song on twitter so you can still be excited,” he wrote. Instead, a shirtless Bieber posted an apology video that included a snippet of some of his new music — and a visit from his little brother and sister. No word on any apology to the Black Keys.
