Floyd Mayweather On Justin Bieber’s Fight: “He showed he ain’t no b***h, he got heart” Rocko Rathon June 9, 2016 Source Sports | Sports News After attending game 3 of the NBA Finals last night, Justin Bieber got into a scuffle in a Cleveland area hotel lobby and footage of the incident has since gone viral. Floyd Mayweather, who is a close friend and mentor of the pop star, has had The Biebs accompanying him to the ring several times and even occasionally trains with him. TMZ Sports caught up with Mayweather while in New York City this morning (June 9) and asked him his thoughts on Bieber’s technique in the video. Though it is clear that Floyd only vaguely saw the video, he did go on to mention that his good pal does have a lot of heart for not backing down to someone who was much larger than him. “I don’t know why he’s fighting but he’s ready. At the end of the day, people will say what they want to say. Justin Bieber ain’t no bitch. He showed he got heart. He showed he ain’t no bitch, so it’s all respect.” Well, the undefeated fighter has spoken.
