Bruno Mars is pulling double duty as both the host and musical guest on Saturday Night Live this weekend. There may be singing, there may be dancing, and there just may be some comedy in there, too. But who knows?!
Of course, since the "Locked Out Of Heaven" crooner is literally and figuratively a man of many hats (and, in the case of this week's SNL promo, so is Fred Armisen) you should probably expect all of the above.
