In a video clip that Katy Perry released for her forthcoming video, 'The One That Got Away', we get a closer look at who will be playing her love interest and a glimpse at the star how we've never seen her before.

The song is the candy-eyed singer's next single, which the teaser clip suggests will be released on November 11. It's about young love that didn't last but remains as one that she can never forget, even when she's much older (as pictured on the left) and sporting grey hair.

Her leading man is played by Mexican actor, Diego Luna, who has appeared in 'Y Tu Mamá También' and 'Milk'. 

As the two stars portray the ups and downs of love in the 36-second clip, a narrator tells their story:

 "The past is like a handful of dust...It filters through your fingers, disappearing little by little...I wish, for one day, I could go back...In another life, I would do things differently".

In an interview with MTV, Perry, who is just about to finish up the European leg of her California Dreams tour, has said that she's excited to share the softer side to her fans:

"I'm so pleased to select 'The One That Got Away' as my sixth single because this song shows a very different side of me that I haven't shown with my past singles on this record. I think that everyone can relate to this song...I wrote this song about when you promise someone forever, but you end up not being able to follow through. It's a bittersweet story — hopefully, the listener learns from hearing it and never has to say they had 'The One' get away".
