This is embarassing. Katy Perry was performing a fun pop version of "Big Pimpin'" and decided to bring a flute on stage and give it a go. It looks like she's nailing it, surprisng the crowd with the unveiling of her hidden talent. Only one problem: she forgets to put the flute to her mouth and the flute music keeps playing. Katy's obviously upset by her mistake and has no choice but to admit that she can not play the flute.
