As is the custom, Floyd Mayweather Jr. was a escorted to the ring for his bout with Marcos Maidana by a rapping MC. As he did for his last fight against Canelo Alverez, the champ chose Lil Wayne and Justin Bieber to flank him as he made his way to the square. Hey, if it aint broke don't fix it. Weezy got a chance to perform his brand spanking new single "Believe Me" (sans Drake) for the first time for a packed out house at the MGM Grand. Mayweather bested Maidana in a tightly contested matchup by majority decision to remain undefeated at 46-0.
