Once upon a time, Floyd Mayweather and Justin Bieber were extremely close friends. Bieber walked Mayweather out to the ring before a handful of fights. He also came to Mayweather’s aid when he was involved in a car accident with his kids. And shortly after Mayweather retired from the sport of boxing following his 49th professional fight against Andre Berto, he was spotted vacationing with Bieber in Bora Bora.

There is obviously a big age difference between the two—Mayweather is currently 40, while Bieber is 23—but it didn’t stop them from sharing a special bond. It sounds like that bond has been broken, though, and Mayweather is not happy about it.

In recent weeks, Mayweather has been asked whether or not Bieber would accompany him to the ring before his fight with Conor McGregor, and he has downplayed questions about it. It led to some speculation about his friendship with the singer. And that speculation increased last week after Bieber came out and said that Mayweather would not knock McGregor out during their fight, which prompted a response from Mayweather’s dad.

And according to a TMZ Sports report released early Monday morning, there is something to all of the speculation surrounding Mayweather and Bieber. The report indicates Bieber is no longer associated with Mayweather’s Money Team and that he and Mayweather are no longer on speaking terms. Sources who spoke with TMZ Sports revealed that Bieber has been receiving counseling from the Hillsong Church in recent months, and during counseling, he has apparently been asked to take a good hard look at who he has been hanging around with over the last few years.

Bieber wasn’t specifically asked to evaluate his relationship with Mayweather, but it seems Bieber went ahead and evaluated it on his own and found that it might not be the best relationship for him to be in. So he reportedly unfollowed Mayweather on Instagram as a way to"reset boundaries" between the two—and as you might expect, that didn’t go over well with Mayweather.

TMZ Sports is reporting that Mayweather went "nuclear" after hearing that Bieber unfollowed him. He also reportedly called Bieber a "traitor" and reminded him that he stuck by his side when he was having legal problems a few years ago. Mayweather is said to be "incensed" over how his relationship with Bieber has played itself out recently.

Mayweather is yet to respond to the TMZ Sports report, but with his fight with McGregor just a few days away, we’re sure he’ll be asked about his friendship with Bieber, or the lack thereof, in the coming days. We're also sure McGregor will find a way to use this against Mayweather in the buildup to their fight.
