What do Justin Bieber and Chris Brown have in common? They can’t ever seem to let things go. The Black Keys drummer Patrick Carney didn’t speak too highly of Justin after he got snubbed from any and every Grammy award this year and the Biebs isn’t holding anything back – in a joking manner.

“the black keys drummer should be slapped around haha,” Justin tweeted early Tuesday morning. So what got him all riled up?

It all went down after Patrick was done celebrating his Grammy wins early Monday morning, leaving Hollywood hot spot Chateau Marmont. TMZ chatted with the drummer, asking what advice he has for aspiring Grammy winners. “Buy a minivan and go on tour,” he replied.

But when asked if Justin deserved to be shut out from the Grammy nominees, he said, “I don’t know… he’s rich, right? Grammys are for like music, not for money… and he’s making a lot of money. He should be happy.” Cue an angry Bieber!

We’re sure Justin was just joking around with his tweet -– kind of. He’s been vocal about showing all his “haters” that he’s here to stay and tried to shrug off the cold shoulder he got from the Grammys this year. “My whole life I’ve dreamed of winning a Grammy,” he told Billboard magazine. “At this point, the excitement of that has gone down. I’m more excited to just make great music for my fans. That’s just something that if it happens, it happens.”
