Peter Andre and his new wife Jordan are allegedly having 'musical differences' during the recording of their new duet album.

The couple are apparently arguing over who sings which part, how it should sound and even what particular style Jordan should sing in.

A source in the studio remarked, "They've been arguing over songs, production and who sings what. Jordan wants soft Dido-style vocals to show off what she calls her 'expressive soulful voice'."

They added, "Pete thinks she should go more disco and wants some hip-hop too."
