Bummer! The crappy weather conditions outside today have sadly forced Jay-Z and Alicia Keys to postpone their planned performance of "Empire State of Mind" at Game 1 of tonight's World Series showdown between the Yankees and the Phillies. Provided it actually stops raining, they'll do the song before Game 2 tomorrow night instead. Until then, we can only assume that these two will be rehearsing in the comfy confines of Hova's stash spot. [Reuters]
