Report: Mayweather went 'nuclear' after Bieber unfollowed him on Instagram

Floyd Mayweather has reportedly deemed Justin Bieber a "traitor" after the pop star unfollowed him on Instagram.

According to TMZ Sports' sources, Bieber has been receiving counseling through Hillsong Church and was advised to distance himself from those who are bad influences. Bieber reportedly unfollowed Mayweather on Instagram in an effort to "reset boundaries" between them, which caused the boxer to go "insane, nuclear."

"He lashed out at Justin, called him a 'traitor' because Floyd had stuck with Justin during his meltdown when everyone was attacking Bieber," the report states.

Mayweather indicated during an appearance on "Jimmy Kimmel Live!" last Tuesday that Bieber likely won't walk with him to the ring for his fight against Conor McGregor.

"He's going through a lot right right now," Mayweather said of Bieber. "I don't think he's really in music like that, he's more into church right now. I'm praying for him and wish him nothing but the best."
