During her San Francisco stop on The Lifetimes Tour on Friday night, Katy Perry had a scary moment when a flying butterfly prop malfunctioned mid-air, nearly causing her to fall into the crowd below. KP is seen struggling to maintain her balance as the prop jerks violently downward, visibly startling her mid-performance. Despite the scare, the she managed to regain her composure and finish the show. She's in Seattle tonight, and I'm sure her folks have the butterfly a bit more stable for the show. One would hope so anyway.
