Nicole Kidman and Keith Urban have nicknamed their daughter "the raccoon".

The 'Rabbit Hole' actress and her country singer husband are amused by their inquisitive two-year-old Sunday Rose's habit of stopping to investigate everything she sees but the couple don't think she will always be so curious about her surroundings.

She said: "Keith calls her the raccoon because she gets into everything, she will grow out of it, she's only two and a half."

Nicole and Keith, both 43, chose the name Sunday Rose for their daughter but the Australian actress doesn't mind when people use nicknames for her.

Speaking on the Kyle and Jackie O show on Australia's 2day FM, she said: "We love the abbreviations, we call her Sunday Rose, Sunny and Sunday."

Nicole has previously revealed she has passed a fascination for exotic animals onto Sunday Rose and the tot loves taking their pet alpacas - which the family raise on the farm they own in Nashville, Tennessee - for walks.

She explained: "We have alpacas on our farm because they're so pretty. They have lovely long lashes. I think they're really cool. I always wanted a mix of weird animals but that's the weirdest we have.

"You can walk them around on a leash and we have a two year old who loves them."
