Katy Perry Perfromance on Xfactor

This is Katy Perry's performance on the show Xfactor she performed a new song called 'Firework'. I thought this performance was good and it shows that she is quite a popular artist as she says at the end that her tour has already sold out. She recently judged on this show so she was nervous to perform to her fellow judges, but seeing as she gained a standing ovation she did pretty well. Katy Perry was interviewed on the Xtra Factor after her performance and she explained to the presenter that the Catherine wheel firework in the background was significance to her name as she is originally called Kathryn.
