Black Keys drummer  Patrick Carney is kicking things up a notch in his Twitter feud with Justin Bieber's fans.

He made Justin's beliebers even angrier than they already were by  changing his official Twitter profile pic to one of Bieber.  He also  changed his profile name to Patrick Bieb Carney, and updated his description to  read "official twitter for the actual verified Patrick Bieb Carney.   Drummer in the Black Keys."

Carney has since changed his profile picture and name back, but his bio still  reads "Patrick Carney (formerly Justin Bieber).

Carney initially attracted the ire of Bieber's 34-million followers  last week when he told TMZ that the teen pop star didn't deserve any Grammy  nominations.  Justin responded by saying that the drummer "should be  slapped around," which his fans were only too willing to do via Twitter. 

Carney didn't seem to mind much, and has been re-tweeting his favorite  insults as they continue to pour in.
