The 'Roar' singer has recorded a song with her boyfriend for his upcoming studio album.

Katy Perry and John Mayer's much hyped duet has emerged online one week before the release of his new album 'Paradise Valley'.

The 'Part Of Me' singer features as a guest artist on John's new album track 'Who You Love', which emerged on Monday (12th August) after a first play in America.

The slow melodic ballad sees Katy and John trading verses before teaming up on the song's chorus, and will feature on the track listing for John Mayer's upcoming sixth studio album.

The pair have been dating on and off for much of the past year, and recently seemed to reconcile after John gave the US star a shout-out during one of his live shows for helping support him through his vocal chord surgery in 2012.

John Mayer's new album 'Paradise Valley' is set to be released on 20th August while Katy Perry is preparing to drop her new album 'Prism' on 22nd October.
