Hip-hop was out in full force yesterday during big boxing matches between Adrien Broner and Carlos Molina, and Floyd Mayweather and Marcos Maidana. First, Rick Ross and 2 Chainzshowed up to walk Mayweather to his pre-match weigh-in, then Ross showed up again to walk Broner to the ring while performing "Box Chevy," and finally, Lil Wayne (along with Justin Bieber) walked Mayweather to the ring while performing "Believe Me," his brand new song from Tha Carter V.

Mayweather's procession to the ring also included some clowns, jugglers and other circus-related characters, only adding to the spectacle. Later, he got Tyrese to sing the national anthem alongside Rev Run and Diggy Simmons. Below, watch a video of Weezy and Bieber walking Mayweather to the ring, via World Star.
