Justin Bieber has shot back at the drummer for The Black Keys, Patrick Carney, following a remark he made after the Grammy Awards on Sunday night.

When asked about Bieber’s supposed “snub” at the awards show–which saw The Black Keys take home several trophies–Carney said, “He’s rich, right? … Grammys are for music, not for money … and he’s making a lot of money.”

Bieber promptly fired back on Twitter.

the black keys drummer should be slapped around haha

He must not be too mad, though, because soon after, he retweeted Stewie Griffin.

Lesson #1: Only trust people who like big butts… They can not lie.
