Katy Perry wowed 16,000 screaming fans with a hit-filled set to round off the first night of the Capital FM Jingle Bell Ball 2013, performing both old and new songs to round off today's (7th December) show.
The US star kicked off her Jingle Bell Ball set with a performance of her debut single 'I Kissed A Girl', appearing from behind a door to make her entrance to the stage dressed in a tasselled pink dress.
During the performance Katy headed straight out to the front of the O2 Arena stage alongside her guitarist for the final chorus of the song, before heading straight into new 'Prism' song 'Dark Horse'.
The 'Teenage Dream' singer was then joined by a troupe of dancers dressed up as Christmas elves as she launched into her 2012 hit 'Part Of Me', before wrapping up in a furry coat for 'Wide Awake'.
Katy then went on to perform another track from her new album 'Prism' called 'Walking On Air' to huge cheers from the crowd, and then went on to perform a medley of her fan-favourite songs 'California Gurls' and 'Teenage Dream'.
