The video for 'Not the End of the World' pokes fun at the resemblance between the famous pair

Over the years - and particularly in the early parts of their respective careers - the physical resemblance between Katy Perry and actress/musician Zooey Deschanel was noted by many.

Now, the pair have joined forces after all these years to poke fun at that fact.

Deschanel features in the video for Perry's new single 'Not the End of the World', which sees a group of aliens who are obsessed with Perry mistaking her for the pop star and beaming her up into their spacecraft - where it's revealed that despite their error, they've saved her from certain death as the planet is about to explode.

Sounds like your average Katy Perry video, to be perfectly honest.

Perry herself makes a cameo pushing a pram; she gave birth to daughter Daisy earlier this year.
