Lady Ga Ga had millions of TV viewers fooled as she had appeared to leap off the top of the stadium and then descended down from suspension wires. But TMZ is reporting that was pre-recorded. Those inside the stadium knew this well judging by some of the fan video that has appeared online.
It also appeared at one point, that she was lip syncing.
But this isn't abnormal for the Super Bowl. Most performances are taped in advance to sound live. The Red Hot Chili Peppers did not even have their guitars plugged in back in 2014.
