Dad’s a country star and mom’s a pretty good song-and-dance woman herself, so it’s no wonder Sunday Rose – the 16-month-old daughter of Keith Urban and Nicole Kidman – is already displaying showbiz talent.

“She sounds quite musical,” Urban, 42, told PEOPLE on Sunday night at the American Music Awards. “I sit her at the piano every morning. We play. We mash the keys together. So hopefully she’ll have a little bit of that.”

With Kidman, 42, in the audience, Urban took home the Favorite Country Male Artist award, which he dedicated “to my wife, I just love you so much, baby girl.” And though the couple have no immediate plans to collaborate on anything other than raising their family, Urban hinted a duet could eventually happen.

“We sort of do our own things professionally, but I love singing with her at home,” he says. “I don’t think anything’s ever out of the question.”
