Nicole Kidman's children want 'dog' not sibling

Nicole Kidman has revealed that though her kids do want them to expand their family, they want to do it with a dog and not a sibling.

While attending the Sundance Film Festival, the 47-year-old Australian beauty, who's married to Keith Urban, said that their daughters Faith, 4, and Sunday, 6 don't want any competition and said they were fine when asked about it, adding that they wanted a dog, E! Online reported.

Kidman, who's a mother of four, considering her kids with former husband Tom Cruise, was promoting her forthcoming movie 'Strangerland,' clad in a monochromatic polka dot ensemble.

The Oscar winner had recently admitted that she would love to have more children with her husband of 8 years, and might as well as her grandmother had her last baby at 49.
