Floyd Mayweather Jr. made his grand entrance into the ring at Saturday’s super welterweight title fight flanked by 50 Cent and Justin Bieber. The pop star made a surprise appearance alongside the Money Team at the MGM Grand in Las Vegas, sporting Floyd’s title belts on his shoulders as 2 Chainz’ “Riot” played. The Biebs proved to be good luck—Mayweather defeated Miguel Cotto and maintained his undefeated record.
