This is all alleged right now but sources say singer Mario was 2-pieced in the face by his former manager and it was all over a girl!
Sources say, Mario is dating Dez, Amber Roses former bff before he scooped her right from under J Irv, ,his former manager.
And the least of all people we would think would get involved in the brawl, got all up in it! Black Eyed Peas front man, Will.I.Am, screamed to the crowd
"Oh Sh*t Oh Sh*t, they boxing, they boxing...."
Hey, Will did give that 2-piece slap to Perez Hilton's face last year, so Will is familiar with this sort of thing.
