Lil Wayne, 50 Cent, and Justin Bieber Celebrate Floyd Mayweather’s Victory

Floyd Mayweather Jr. celebrated his win over Cotto at Saturday’s fight with some hip-hop heavyweights and a pop megastar. The undefeated champ took his victory lap in Las Vegas with 50 Cent, Lil Wayne, and Justin Bieber, who walked him to the ring and held his title belts.

The “Boyfriend” singer spoke highly of his friend Floyd in a recent interview. “He’s the best boxer in the world,” he told V magazine. “When everyone else just chills and doesn’t work out because they are not fighting, he’s in there punching the bags because he wants to be the best. He wants to be better than Muhammad Ali, and that’s what he’s striving to be.”

When he’s not on stage, the Biebs enjoys boxing. “Me and my friends box all the time,” he said. “My dad is a fighter so he taught me some stuff growing up, and he’s a great fighter, so I’m a pretty good boxer.”

Other fight night sightings included Mariah Carey, Busta Rhymes, Diddy, Birdman, and Jermaine Dupri.
