Justin Bieber vs. The Black Keys and Drake Bell
After The Black Keys' Patrick Carney dissed the Biebs' musical talent, Bieber replied that the drummer needed to be "slapped around." Carney revamped his Twitter account to mimic Bieber's and unleashed a series of sarcastic tweets mocking the singer's fans. Drake Bell also used Twitter to call out Beliebers and taunt the pop star, prompting multiple death threats to be sent Bell's way.
