Don't look for Keith Urban's wife to singe any more duets with him in public anytime soon. Although Nicole Kidman has proven she can hold her own as a singer in the films Moulin Rouge and Nine, she's a bit more shy about performing with her husband who sings for a living. Nic tells Digital Spy that the recent duet with Keith in tribute to actor Simon Baker at the G'Day USA Ball was just a one time thing! She notes, "It was our first collaboration and probably our last." She elaborates, "If we're just at home and you're playing music and hanging out then I'm fine. If it's professional, then I get nervous. I need to be loosened up."

I vote for another duet!  I'd love to hear one from them.  I know sappy love can sometime be sickening sweet, but I love them together.  That is saying a lot because until she was with Keith I was soooo not of fan of hers.  ~Vanessa
