VIDEO: Will Smith takes the stage with Nas!

It started as just an introduction in his hometown of Philadelphia, but later Will Smith appeared on stage in a wife beater, looking just like the Fresh Prince we knew decades ago.

“The King of Philly” introduced Nas and Damian Marley at the beginning of the show, and returned later to perform and hype up the crowd!
