In case you’re curious, Justin is scheduled to drop in on Chelsea Handler tonight, and you can bet she’ll be quizzing him on his whereabouts for the past several years.

Speaking of missing-in-action, anybody remember Arsenio Hall? Didn’t he used to have a talk show or something? If you want the scoop on him, you can catch him on the couch next to Jay Leno this evening.
