Justin Bieber: Floyd Ain’t Knockin’ Out Conor McGregor

Justin Bieber Floyd’s My Boy, But … He Ain’t KO’ing McGregor!

Even Floyd Mayweather‘s closest friends don’t think the boxer has a real shot of knocking out Conor McGregor next weekend … just ask Justin Bieber. 

Mayweather told the media last week he’s gunning to finish the UFC star long before the 12th round when they clash on August 26. Tons of boxing experts are also predicting a K.O.

But not Biebs. 

The singer hit up Runyon Canyon for his own workout when he poo-poo’d the knockout talk — though it’s clear he’s still pickin’ Floyd to get the W. 

Bieber’s been hardcore Team Mayweather for years — and even walked the boxer into the ring for the Pacquaio fight.
