Gaga never lipsyncs. I know her stage performance style. Most of all songs she sang, no lipsync effects. The audio voice and her voice mixed up while singing. I can still hear her voice. And sometimes she screams and shout out loud to command her fans to put their paws up, proof that she doesn't lipsync.
She has, she burnt herself once ,she had to miss a few songs but luckily she had bandages around her leg so she was able to perform the last song which was shout out to my ex.
