Katy Perry Performing On Idol This Week!


Before she heads down under next week, we've learned that Katy Perry will be performing on the American Idol results show this Thursday! KP will belt out her latest smash single, E.T., but there is no word yet if Kanye West will be joining her.

Do it, Ye! The last time we heard you on Idol…Kris Allen was singing Heartless!

Too long! You've got to show'em how it's done!
