Los Angeles: Pop star Katy Perry has sung about past relationships in upcoming music video single 'The One That Got Away'.

The 27-year-old wife of funnyman Russell Brand, poses as an old lady who recalls the time when she was young and free. She remembers going through the ups and downs of a relationship with the man of her dreams, as reported.

"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," Perry said.

The music video was filmed in early October. Starring Mexican movie star Diego Luna as Perry's lost love, the clip is going to be premiered in full on November 11.

'The One That Got Away' is taken from Perry's 2010 summer album 'Teenage Dream'.

"I'm so pleased to select 'The One That Got Away' as my 6th single because this song shows a very different side of me that I haven't shown with my past singles on this record," she said.
