Ellie Goulding -- Rolls Bus Over Sound Guy in Lip-Syncing Football Fiasco (VIDEO)

Ellie Goulding took some serious shots at her audience and in particular the sound guy who she says screwed up royally during her performance at the Australian Football League pre-game show ... exposing an egregious case of lip-syncing.

Ellie was performing her hit, "Love Me Like You Do," before the championship game ... at least that's what she was scheduled to do. But you hear the music and her voice, but the mic is nowhere near her mouth.

Ellie went on Twitter after the game and [said, "Considering i had no voice yesterday and a sleepless night because of the meds I would say it's been a good day." Then she took her first shot, saying, "I give 100% in my performances, even when people don't give much back."

But her real wrath was reserved for the audio tech, saying, "Incidentally the sound guy who pressed playback twice and triggered both band tracks simultaneously is nowhere to be seen."
