Keith Urban, Nicole Kidman’s Daughters Develop Unique Accents

Nicole Kidman is hoping her two youngest daughters, Sunday Rose, 4, and Faith Margaret, 2, follow in Dad Keith Urban's musical footsteps. And it seems like they are off to a good start!

"I'd love it," Nicole said during an appearance on "The Ellen DeGeneres Show." "The great thing about being married to a musician ... you have music in the house all the time, so there is something very joyful about having music. Keith can play pretty much any instrument, so he'll just play piano at 7:00 in the morning, and we have breakfast around the piano. It's very much a part of our life."

The family now resides in Nashville but have spent plenty of time in Australia, which might explain their daughters' unique language. "They have a mix of Australian and Southern, which is really cute," Nicole explains. "My mom always says, 'I can't understand her!' Because she says 'hey y'all' to her grandparents."

The little girls may eventually add a little west coast dialect to their speech, since their dad is about to begin his stint as an "American Idol" judge this week. Season 12 premieres Wednesday, Jan. 16 at 8:00 PM ET on FOX, with another episode airing Thursday (Jan. 17).
