Justin Bieber Defends Floyd Mayweather Jr.

Justin Bieber came to boxer Floyd Mayweather Jr's defense after walking the latter to the ring Saturday night.

Mayweather, 36, beat a formerly undefeated Canelo Alvarez, 23, in a majority decision ruling. After one of three judges called the fight a draw, Bieber, 19, spoke out on Twitter about the matter after walking Mayweather to the ring for the big event.

"Who calls a draw? That guy was watching the wrong fight," Bieber tweeted. "@FloydMayweather is the greatest. #MoneyTeam still #undefeated."

Mayweather has appeared more humble in recent post-fight interviews by thanking God along with his opponent. Even before the light middleweight championship superfight, the fighter took to Twitter to give reverence to God.

"Without GOD -- none of this is possible," he tweeted. "Thank you for your love and support."

Bieber was there to support Mayweather throughout the fight which he first did during the boxer's Miguel Cotto fight last year. The two reportedly became friends after the pugilist saw Bieber's movie, "Never Say Never" and wanted to reach out to the singer.

TMZ reported that Mayweather, nicknamed "Money" and "Pretty Boy Floyd," wanted to mentor the 19-year-old boxing fan. Sources told TMZ that Mayweather has been trying to share his work ethic with Bieber and teach the young singer that he could achieve the same level of success.

Although many considered Bieber's appearance shocking, the young singer spoke about the similarities between he and Mayweather along with his admiration for the fighter in an interview with V Magazine last year.

"Everyone wants you to be on top, and as soon as you're there -- like Floyd Mayweather, he's the best boxer in the world. Now he is a champion," Bieber told the publication. "Every time he goes to a fight now, people are like, 'He's going to lose this time,' and then he wins. And the next time they say, 'He's going to lose,' again ...Every time he wins. And people aren't ever going to know that he's a champ."
