The 'I Kissed A Girl' star and her musician ex-boyfriend called time on their relationship recently.

Katy Perry and John Mayer ended a seven month romance this month – which was confirmed by the musician during a chat with Ellen DeGeneres.

It had been claimed that Russell Brand was one of the key factors to the romance not working out, as reports emerged of John's jealousy of Katy's ex-husband.

E! News have claimed that their hectic schedules meant trying to keep things private turned ultimately too difficult and they felt it necessary to end things.

"John still very much loves her and has feelings for her," a source told the publication. "It was just going to be too much with what was on his plate."

John has recently announced details of his first solo tour in three years and Katy is set to start work on her new album.

Speaking to Ellen, the 'Half Of My Heart' star admitted the pair shared a "very private" relationship but conceded that "coupling is hard".

The 'Firework' singer is yet to break her silence on the break-up but has been seen making some high-profile appearance, including at the Nickelodeon Kids' Choice Awards.
