Katy Perry has treated fans to a behind the scenes look at her 'This Is How We Do' video.

The singer released the track in August as the latest cut from her 2013 album 'Prism'.

Its video has proved popular online and a making of clip has now been released by Perry.

It sees the US star go through a number of costume changes as she gets to grips with the colourful video.

Perry sums up in the clip: "All around, I would consider this shoot very flossy."

'This Is How We Do' meanwhile follows up the previous 'Prism' singles 'Roar', 'Unconditionally', 'Dark Horse' and 'Birthday'.
