Katy Perry has released the video for her new single, 'The One That Got Away'.

The Californian singer is barely recognisable as she goes for granny chic whilst singing about a young love.

The emotional song sees Perry reminiscing about a relationship that ended it tears and tragedy when her onscreen lover, played by Diego Luna, who has appeared in films like 'Y Tu Mamá También' and 'Milk', crashes his Mustang after the young couple have an argument.

The video ends with an aged Perry standing in the spot where he died as Johnny Cash's 'You Are My Sunshine' plays in the background.

Check out the video for Katy Perry's 'The One That Got Away' and a live performance of 'Teenage Dream' on Live on Letterman:
