Katy Perry has unveiled the video for her new single ‘Firework' - you can watch it below now.

The video shows fireworks erupting from Perry’s chest as she stands on a balcony overlooking a European city.

As the video continues, fireworks also begin to shoot from the chests of dancers.

Launching the video on Twitter, Perry said: "U have the spark too, now ignite the light..."

‘Firework’ is the latest single to be taken from the singer’s chart-topping second album ‘Teenage Dream’.

Meanwhile, Perry is set to embark on a UK tour next year in support of the record.
