Justin Bieber wants the world to know he is an adult and is ready to do adult things. One of those things happens to be supporting one of the toughest boxers in the sport. Justin's cutesy looks and seemingly innocent personality are not usually associated with professional boxing, but the Canadian singer is doing everything he can to toughen up his image.
Last night, the Biebs joined forces with rap bad boys 50 Cent and Lil Wayne to support Mayweather. The small group, also known as the Money Team, were there to cheer on their champ. Justin surprised the crowds at the MGM Grand Garden Arena when he walked into the ring before his match with Miguel Cotto.
Justin joined Mayweather in the locker room before the fight for a little pre-match chit chat. The "Boyfriend" singer was nearly hidden underneath the massive championship title belts as he walked with Mayweather's high-profile entourage into the ring. After the win, Justin Bieber once again climbed into the ring and posed for pictures with the burly boxer and his rapping pals.
Justin seems to be working pretty hard at dispelling that squeaky-clean image he has worked so diligently to build up. Will his tougher side attract more fans or will it end up backfiring?
