This weekend, Will Smith was apparently in a great mood at Gabrielle Union's birthday bash. He worked through the "Fresh Prince of Bel-Air" theme song and "Summertime." He also freestyled over Doug E. Fresh's beatboxing and this is a rarety for Will Smith and the performance was surprising not so much for it being unexpected but Smith used both 'b---h' and the n-word, big departures for the squeaky clean rapper.
