Justin partied with the crowd before walking out with Floyd Mayweather, and at 33 seconds you can see him mouth the words, “f*** Pacquiao” … he then flips the bird.
He was revved up in Vegas before the fight … singing to Big Sean — which is surprising — and making his feelings about Manny Pacquiao clear
It’s also interesting he’s felling Big Sean, whose breaking with Ariana Grande did not go well. You’ll recall he just gave her a squeeze from behind a few weeks back, which set Sean off. We’re told Sean doesn’t have hard feelings for Biebs … he thinks Ariana has a huge crush on him though.
Bieber sure knows how to have fun.
