Justin Bieber, 50 Cent Join Floyd Mayweather Jr.'s Entourage For Title Fight (VIDEO)

Boxing champ Floyd Mayweather Jr. really knows how to make an entrance. The undefeated fighter enlisted Justin Bieber, rappers 50 Cent and Lil Wayne and the wrestler HHH as honorary members of his entourage on Saturday night at the MGM Grand Casino in Las Vegas for his welterweight title fight against Miguel Cotto.

Bieber and 50 Cent carried Mayweather's championship belts to the ring in pre-fight introductions and sat ringside to take in the festivities, in which Mayweather defeated Cotto in a 12-round unanimous decision. After the fight, they took to the ring again to celebrate with the bruised champ.

Bieber, an avowed boxing fan who's struck up an unlikely friendship with the brash and outspoken Mayweather, congratulated the champ after the fight.
