Will Smith stopped by The Late Show with David Letterman last night and treated audiences to a performance of his party jam "Gettin' Jiggy Wit It." As he walked onto the stage, the house band played the instrumentals for the song. Instead of sitting down next to Letterman's desk, he made his way over to the band to pick up a mic and rap along. He even included the audience for the "na na na" parts.

Letterman loved the impromptu performance, but told Smith that he could never rap himself. Smith, however, insisted that Letterman in fact did have the ability. "You can, Dave! It's in you," he urged. "There's a negro inside of you Dave!"

Slightly taken aback, Letterman joked, "I gotta run home and surprise the wife!"

During the segment, Smith also took the time to list the Top 10 things he'll miss about Letterman when he leaves his post at The Late Show.

The actor/rapper mentioned their "electric sexual chemistry," the fact that Letterman still tries to pull off "Harry Potter glasses" at his age, and how much he'll miss "how the wind whistles through that cute little gap in your teeth every time you say, 'Smith.'"

This impromptu performance could just be the beginning of a rejuvenated music career for Smith after a 10-year hiatus. Earlier this month, he revealed that he's been working with Kanye West in the studio and taking pointers from his musically inclined son, Jaden.

"I went into the studio with Kanye. I'm thinking about it. I'm exploring," he told the Guardian. "I'm not sure what I'm going to do yet but I'm exploring. I'm in a creative ceiling. My son tells me I have to write out the things I don't like. I can't write and stop -- I have to keep going and going and write them out. I've never worked like that before, but I think I might give that a shot."

While you await more news on his music career, you can see him flex his acting muscles in the upcoming film Focus, in theaters Feb. 26.
