While performing "Partition" during a recent On the Run show in Paris, a fan filming Beyonce caught a candid moment that appears to show her not singing.
In the beginning of the Instagram video, her mouth movements seem to be totally in sync with the music, but when she leans over to greet the audience, the vocals continue even though her microphone is nowhere near her face.
While it's common for artists to use backing tracks especially while performing choreographed dance routines, this isn't the first time Bey's been busted faking it.
When performing at President Obama's inauguration, the 33-year-old admitted to not singing live, claiming she didn't have enough time to practice.
Do you think it's a big deal that Beyonce lip syncs or should people just let Queen Bey be?
