Justin Bieber Parties in Las Vegas & Attends Floyd Mayweather Fight

Justin Bieber sat ringside at the Floyd Mayweather vs Andre Berto fight in Las Vegas last night, September 12. The fight was held at the MGM Grand, where Justin was spotted backstage with Floyd before his match.

Yesterday, Justin also joined Rich Homie Quan on stage at a pool party Rich was playing in the city. You can watch videos of Justin on stage under the jump.

It looks like Justin had quite the weekend in Vegas. I hope he enjoyed the pool party yesterday and with the win from Mayweather, you know he had a good night!
