Floyd Mayweather Jr 'harassing Andre Berto with phone calls about his ex'

Pound-for-pound boxing king Floyd Mayweather Jr has been accused by fellow fighter Andre Berto of harassing him with constant phone calls.

The undefeated boxer, who is believed to be considering taking on Berto in his next fight, is said to be regularly contacting the American, but never speaks when the call is answered.

Berto told TMZ: "I know it's him on the other line. I can hear him breathing on the other end of the phone. Stop getting people to call my phone bro, and asking me about this person and that person.

"Don't do that shit. That shit is lame, it's corny. He has too much money for that."

The report claims that Mayweather is unhappy that Berto has a friendship with his ex-fiancee Shantel Jackson and her new boyfriend Nelly.
