Rossdale refuses to duet with Stefani

Rocker Gavin Rossdale has insisted that he'll never duet with his wife Gwen Stefani.

The former Bush frontman told MTV that a collaboration with the No Doubt singer would draw unwanted attention to their private life.

He said: "It's bad enough with the whole intrusive, paparazzi-celebrity-weird-photo life. I like mystery. The people I care the most about, whether it's in music or films or art or whatever, I don't really need to know anything about them.

"The less I know about them, the better, because then I can just have my own unfiltered image of them, and whatever they do publicly, for me, can just work its magic. When we get burdened by people at Starbucks, it just takes away from that mystery."
