I'm glad she was able to laugh at herself because that was funny as hell. As far as her 'professionalism' for continuing on with the show; she better have continued. If she can keep singing while audience members are practically on fire she better keep singing after taking a tumble down a few steps. There was no reason for her to stop. She did not break any limbs or faint from dehydration, so hell yeah she kept going. I would not have expected anything less.
