Floyd Mayweather's musical ties have expanded the size of his Money Team. Before his blockbuster victory over Saul "Canelo" Alvarez Saturday night (Sept. 14), Floyd had Justin Bieber and Lil Wayne walk him to the MGM Grand ring in Las Vegas. Weezy even treated the crowd, which included Diddy, Magic Johnson and Kevin Hart, to a performance of his 2008 cash cut "A Milli" as the entrance theme. R&B singer Tank also lent his vocals to the National Anthem. Peep footage from the pre-game show below.
