The reaction was so, er, swift, that MTV was forced to take the unusual step of releasing an official statement.
They denied the pop superstar had broken wind, and said there was "no possibility" of their mics picking up a fart.
The noise was blamed it on a different microphone.
"MTV can confirm that the sound heard in the moment Taylor Swift introduced her new music video, Wildest Dreams, was isolated to a production microphone," organisers said.
