Video: Katy Perry Livin' The Teenage Dream

Hold on to your purple wigs. Just when I thought Katy Perry had already released the catchiest pop hit of the summer, here comes the equally infectious single 'Teenage Dream'.

The video was filmed in her home town of Santa Barbara and stars actor/model Josh Kloss (you might remember him from 'The OC') and a multitude of her real life friends frolicking on the beach.

View it for yourself after the jump - but I must warn you - the scenes of them rolling around in a sleazy hotel room were hot enough to melt my popsicle!
