Keith Urban and Nicole Kidman love performing duets.
The country singer admits he would never rule out a collaboration with his actress wife - who showed off her vocal talents in 'Moulin Rouge!' - because they have so much fun singing together at home.
He said: "Would we do something together? I don't think it's ever out of the question. I don't know. We sort of do our own things professionally. But I love singing with her at home. It's quite nice. She's a huge inspiration for everything I do."
Nicole, 42, may not be the only member of his family Keith collaborates with in future.
The singer also revealed that the couple's 16-month-old daughter Sunday Rose is already showing signs of musical talent.
He explained to America's OK! magazine: "She's got some pipes. They're loud, you know! I think so. I think she sounds quite musical. Sit her at the piano and play and we mash the keys together."
Keith, 42, revealed earlier this year that he and his writing partner Rick Nowels had delighted Nicole by writing a song about her.
Speaking about the heartfelt track 'Thank You' - which includes the lyrics 'I thank God for grace and mercy, and that you became my wife' - Keith said: "Rick's music pulled this story out of me, which became quite a confessional - much more intimate than I might have written had I intended to write about her. It was very instinctual and very much from the heart. We did a quick recording of it, and I took it home and played it for her that night. I think she was very touched."
