Nicole Kidman refuses to sing in front of her musician husband. The 41-year-old actress - who is currently filming musical movie "Nine" - is far too embarrassed to show off her voice in front of country music star Keith Urban as she is afraid he would mock her.
She said: "I will never, never sing in front of him. I wouldn't even play him the track of me singing. Sometimes I might hum in front of him but that's it. Keith is pretty tough with that kind of stuff. He's highly musical."
