NICOLE Kidman and her country music star husband Keith Urban stunned the audience at an event for Aussies in LA by singing a duet — but the actress insists it’s the one and only time the couple will perform together in public.
Kidman — who raises daughter Sunday Rose with Urban — says she and Keith spent their spare time working on a song for pal Simon Baker, but they won’t be making a habit of sharing the stage.

“We decided to do that little turn for our friend Simon Baker,” said Nicole, who has sung in movies Moulin Rouge and Nine.

“We worked on it for about a week at home in the evenings. It was our first collaboration and probably our last.

“If we’re just at home and your playing music and hanging out then I’m fine,” adds the actress on her singing talents. “If it’s professional then I get nervous. I need to be loosened up.”
