Justin Bieber, Lil' Wayne, And 50 Cent Are In Floyd Mayweather's Corner During Miguel Cotto Match!

This must have been so, SO cool!

While many celebrities were on hand last night in Las Vegas for Floyd Mayweather's victorious fight against Miguel Cotto for the WBA Super Welterweight Championship of the world, a few select musicians were included as part of the boxer's entourage - like 50 Cent, Lil' Wayne, and Justin Bieber!

Ch-ch-check out a photo of the pop star holding the belt after the match (above)!

He took to Twitter yesterday to share:
