Boxing Mayweather Champ Defends Bieber

(Undated) -- Boxing champ Floyd Mayweather is sticking up for his friend Justin Bieber, who's taking some heat for dropping the N-word back when he was 15-years-old. Mayweather, who's black, issued a strong defense of Bieber in a photo posted online. He said the Canadian pop star has been nothing but kind to him and his family and making mistakes is just part of growing up. Mayweather added he's proud of the work Bieber's doing as a 20-year-old musician and business man. Over the weekend a video leaked that shows a younger Bieber cracking a racist joke.
