After Conor McGregor’s loss to Nate Diaz, pop star Justin Bieber took to Instagram to praise McGregor for being “a true champion” while shitting on Nate Diaz for having a “terrible fighting style”

Diaz wasn’t too pleased about Bieber’s remark and fired back with an Instagram pic of his own.

It’s probably not wise for Bieber to talk shit to a UFC fighter who could kick his ass in about ten seconds flat.
