Eccentric singer Lady GaGa will return to the American Idol stage as one of the most exciting and successful artists of our time to perform her latest single, “Telephone” (watch official music video here) during the results show on May 5, 2010. “Little Monsters”, mark your calendars!

GaGa tweeted on Saturday (April 17), “See you on American Idol. MAY 5th, Little Monsters,” adding a link to a performance of “Telephone” on YouTube. We are only disappointed GaGa won’t be a mentor because it would be the freakiest, most fun experience for the Idol hopefuls. Of course GaGa is a busy girl!

The 24 year-old singer first appeared on the show to perform her single “Poker Face” about a year ago before GaGa’s world domination began (watch GaGa’s “Poker Face” on Idol video below).
