Online shots have been fired in the feud between Justin Bieber and Patrick Carney.
It all started last weekend, when The Black Keys drummer said Bieber should not worry about his lack of Grammy nominations because the event is based around music, not money.
"And he's making a lot of money. He should be happy."
Translation: Bieber makes crappy music.
Justin then replied that Carney should be slapped for the comment, which has led Carney to make the above change to his Twitter profile.
Carney's handle is now Justin Bieber and his description is now the official twitter for the actual verified Justin Bieber DOS virtual buddy.
As you might expect, Bieber's fans are less than enthused over this slap in the Twitter face.
They have taken to the social network and referred to Carney as a "dick" and as "immature," among other insults.
No public word yet from Justin himself, but why even bother? He can just let his millions and millions (and millions) of followers do the job for him.
