Don't expect him to be anywhere near the T-Mobile Arena in Las Vegas.
According to TMZ, Biebs' new friends at the Hillsong Church have been pressuring him to get rid of the bad influences, and the singer decided Mayweather was on that list.

Justin didn't want a clean break from Floyd. Instead, he wanted to "reset boundaries" and avoid things like Floyd's obsession with strip clubs.
So he unfollowed Floyd on Instagram.
When the undefeated champ realized Biebs broke up with him on social media he apparently went "insane" and "nuclear."
He believes Bieber is "traitor" for ditching him when he was the guy who always defended the little Canadian when everyone else was attacking him.
We wonder if Floyd will have enough fury left for McGregor on Saturday.
