Lives were potentially saved, though Katy Perry is being a bit facetious when she’s thanking the team for saving her life.
Perry was hamming it up a bit while waiting to get back into the building and “collapsed” to the ground.
She was later given a pulse oximetry for her finger, and a short time later leapt up to hug the firefighter for “saving her.”
For anyone questioning how serious the situation was, check out the video and pictures posted of Perry to her own account of her recovering on the ground.
