Justin Bieber made a surprise appearance over the weekend when he accompanied boxer Floyd Mayweather down to the ring for his scheduled match on Saturday (14th September).
The 'Boyfriend' singer walked side-by-side with champion Floyd alongside a rapping Lil Wayne, as the latter performed 'Millionaire' while they headed down to the MGM Arena ring in Las Vegas.
Justin also helped Floyd celebrate after his win over Canelo Alvarez following the match, as well as hanging out before and after the match backstage at the arena.
"Who calls a draw? That guy was watching the wrong fight. @FloydMayweather is the greatest. #MoneyTeam still #undefeated," Justin posted in response to the match result after.
