James Franco Jammin'!

And when we say jammin’, we mean it! Bob Marley would sing his praises!

Last night, James Franco attended the 2nd Annual Rob Pruitt Art Awards and took to the stage to perform a rousing duet with artist Kalib Lindey.

Webster Hall didn’t know what hit it!

Looks like he really got into his performance, but what is with his outfit? Did a Chippendales from 1987 have a fire sale?

Check out the rest of the pics from his performance (below)!

He’s a puzzling one that James Franco.
