Who Knew Justin Bieber & Rihanna Were Such BFFs?

By  | 

We already knew Justin Bieber had a lot — and we mean a lot — of famous friends. But we didn’t know he was total besties with Rihanna until we spied them hanging out front row at the NBA All-Star game.

We’re sorta hoping they were fist-pumping to a future collab. Thoughts?

Rihanna has collaborated with everyone under the sun — except JB — and we think they would be a truly epic duo. Would you like to see them team up?
