OH dear. Pop star Pete Doherty, above, has fallen into a dangerous trap.

By blurring the lines of romance and career he is following the deeply grooved path left by broken bands and often relationships as well.

The badboy Babyshambles' singer is now writing songs for the group in collaboration with his girlfriend model Kate Moss, and the other lads don't like it.

The two are reported to be working on an album, inspired by traditional love poetry and other writing.

This, surprisingly, has apparently not met with approval from the other three members of the group.

Paul McCartney annoyed both fellow members of Wings and their fans when wife Linda swapped her vegetarian kitchen for keyboards and performed with them on stage.

Working with the love of your life is always a charming concept - perhaps best left as just that in most jobs, especially if you're a pop star who wants to keep his professional reputation intact.
