Justin Bieber's feud with Black Keys rocker Patrick Carney has continued after the drummer impersonated the Baby singer on Twitter.
Patrick sparked a row with the Canadian teen idol after he hit out at him at the Grammys, and ended up getting hundreds of abusive messages from Justin's fans.
The drummer responded by changing his Twitter name to Justin Bieber, using a picture of the singer and posting spoof messages such as: "Gurl u give me inspiration to make my music and toothbrushes and all thatz swag to u baby."
After changing his online identity back, Patrick wrote: "Only thing I remember from being Bieber is that I was really thirsty the whole time."
The feud began when Patrick was asked on the Grammys red carpet why Justin wasn't nominated and replied: "He's rich, right? Grammys are, like, for music, not for money, and he's making a lot of money."
Justin later tweeted: "The Black Keys drummer should be slapped around."
