Justin Bieber: 'Black Keys drummer should be slapped'

As if the pain of being shut out of the Grammy Awards and then watching his attempt at counter-programming fizzle wasn't enough, now Justin Bieber as to contend with backhanded jabs from someone who picked up a couple pieces of hardware
 on Sunday night.

After Black Keys drummer Patrick Carney tossed off some jokey offhand stabs at the Biebs on TMZ after the Grammys, Bieber took to Twitter on Monday to get his revenge.

"The Black Keys drummer should be slapped around haha," Bieber tweeted early Tuesday (February 12) morning. What got Bieber so (jokily) heated?

TMZ caught up with the straight-talking Carney as he was leaving Hollywood's Chateau Marmont early Monday morning and asked him if he had any advice for aspiring Grammy winners of the future after his band took him three awards. "Buy a minivan and go on tour," he said. When the cameraman pressed harder and asked for Carney's take on whether Bieber deserved to be snubbed by Grammy voters, the amiable skins pounder shrugged and said, "I dunno ... He's rich, right? Grammys are for like music, not for money ... and he's making a lot of money. He should be happy."

When MTV News spoke to Bieber's manager, Scooter Braun, last week,
 he said he was done talking about how the Recording Academy had missed the boat
 on his biggest client.

Bieber was still clearly feeling the sting over the weekend, though. As a kind of counter-programming to the big show, the Biebs had planned to hold a live stream chat
 with fans, but when things went haywire and the stream failed, he junked the idea and later offered a new, unfinished song titled "You Want Me" 
in its place.
