Wait. This is a controversy?
Sorry, but I simply assumed that she had been lip-syncing, since it was so damn obvious. I watched this through Korean television, but I assume that everyone else in the world had the same feeds from the closeup cameras. I thought, "That's a cute kid. Too bad she's lip synching. I guess they went for cute over talented."
She over-gesticulated with her mouth and seemed to be concentrating on her super-smile the entire time. I didn't know anyone had been "fooled."
Were we really watching the same feed in Korea as in other countries?
