Peter Andre's next single appears to be about his ex-wife, Katie Price.

The Australian born singer's next single is called 'Mercy On Me', and its lyrics appears to reflect on his relationship with Katie, whom he split from in 2009 after four years of marriage.

Lyrics include: "A fairy tale that fell apart / I'm sorry but my heart's still in two halves.

"Ever since the day our eyes met / I had made a promise / To be there forever more.... Dear Lord have mercy on me / Cos I can't forgive the things that happened yesterday."

Glamour model and reality TV star Katie - who has since remarried - also admits in her latest autobiography that she'd like to meet up with Peter to discuss what went wrong with their union.

Relationship expert Judi James told the Daily Star newspaper: "Katie and Pete are clearly still mad about each other, they will always see themselves as a couple.

"They are sending out tentacles to each other through their books and music and it's clear that they can't let it drop."

Peter is currently on a promotional tour of the UK, but will later in the month tour 'Defender', with support provided by new vocal harmony group The Overtones.

Discovered while working as A Team of painters and decorators, The Overtones sing a range of vintage influenced covers, and their debut album, 'Good Ol' Fashioned Love' was released on this week and is available now.
