Lady Gaga Performs on American Idol | Watch Online Streaming

American Idol narrowed its field of finalists to four last night by eliminating Aaron Kelly, but the highlight of the night was a performance by Ms. Lady Gaga. Ratings are way down this season, but that can't be blamed on the show's roster of results night guest performers, which has been consistently impressive. Gaga's pre-taped performance, which has been widely anticipated, ran over six minutes in length, but due to time constraints, was cut down to under five.
