Lady GaGa announced via Twitter that she's set to perform on American Idol on May 5th!

Last week, our idol tweeted that she was going to be appearing on the show next month, with a link to a (now removed) video of GaGa's performance of her new single, Telephone on a Japanese television show. Guess we can expect our phones to be ringing!

Unfortch, the 5th is the elimination episode, which means GaGa will merely be a performer and not a mentor, but maybe that's a good thing. Can you imagine Big Mike wearing nothing but a unitard and 5-inch platform heels?
