Justin Bieber is a lover, but he's pals with a fighter. The 'Beauty and a Beat' will walk boxer Floyd Mayweather, Jr. to the ring to hopefully deliver a beating to his opponent, Saúl "Canelo" Alvarez.

TMZ reports that Bieber previously flocked Mayweather last year when the champ fought Miguel Cotto. Rapper Lil Wayne, a mutual pal of Mayweather and Biebs, was also on hand. Bieber and Weezy were present to present Mayweather with his hard-earned championship belt.

It turns out their friendship extends past the boxing ring, too. Mayweather reportedly invited Bieber to his 13-year-old daughter's birthday party, flying him out for the event. So cute!

Biebs will escort Mayweather to the ring this Saturday at the MGM Grand in Sin City. We guess he has enough cash to hang with Money May!
