Katy Perry went from banana to Father Christmas during a performance in California over the weekend.

The singer wowed fans with an impressive array of costume changes at the Jingle Ball in Anaheim.

Perry, who played a short set which included her massive hit 'I Kissed A Girl', was one of a host of performers at the event.

American Idol host and radio DJ Ryan Seacrest hosted the annual ball.
