Justin Bieber has made his opinion clear that he is #TeamMayweather and definitely has nothing to do with rival, Manny Pacquiao.
The Biebs thrilled the crowd before walking Floyd Mayweather into the ring for his huge game against the Filipino boxer in Las Vegas on Saturday, May 2.
But few seconds into his performance, the pop star's lips could be seen saying... ''f**k Pacquiao''.
Other reports claim he also dissed rapper Big Sean who recently sparated from girlfriend, Ariana Grande after the Biebs hugged her from behind at her concert in Detroit last month.
However Sean cleared the air saying he doesn't have any hard feeling towards Bieber but believes Ariana used the singer to hurt him.
