If you thought Lady Gaga's performance on Wednesday night's American Idol results show seemed more bizarre — and sleepy — than usual, you're not alone: Gaga herself is steaming mad! "FOX POORLY + AMATEURLY edited+cut my performance/musical arrangement on idol" Gaga wrote on Twitter, also noting that the show cut her act, which was taped in front of the studio audience after Tuesday's live show, in four places. It's a shame, says an insider. "Gaga worked hard on the performance, rehearsing and stage blocking till 9 on Tues night after the Idol performance show. She also worked hard on her dancing for this one," the insider tells In Touch, adding that the performance, as originally conceived, would have blown minds. "It was to be quite the blood-splattered epic," the insider tells In Touch, adding that it was expected to cause "some Madonna-esque backlash a la 'Like A Prayer,' as it had a lot of religious overtones and ends with her covered in blood and being put into a fountain to be cleansed. Also, the male/male dancing might have caused quite a stir." Unfortunately Gaga's version ran over six minutes, so Idol — which often runs late anyway because of the live portions of the show — simply cut it out.
