Justin Bieber had some fun before Floyd Mayweather’s match at the MGM Grand Garden Arena in Las Vegas last night, September 12. Justin was there to support Floyd in his match against Andre Berto.

Justin shotgunned a beer pre-fight with a pal and was ringside as Floyd won his fight to remain undefeated. After the match, Justin dropped by XS Nightclub to hang with DJ Diplo.

Fun night!
