Nas and Damian Marley’s Philadelphia show got a boost of star power when hometown hero Will Smith hit the stage last night at the Electric Factory. Wearing a wife-beater and jeans with a rag in his back pocket, the Hollywood megastar introduced the Distant Relatives before joining Nas onstage for “Made You Look,” as his son Jaden looked on.

“The king of Philadelphia!” proclaimed Nas of the rapper-turned-actor, while billing himself as “the king of New York.”

Nas released his new single “Nasty” to iTunes this week. His 10th solo album Life Is Good is due this fall.
