Nicole Kidman has shared a photo, showing her dozing beside her baby daughter Sunday Rose, during an interview with US talkshow queen Oprah Winfrey.

On Winfrey’s encouragement, Kidman shared the photo, taken by her country singer husband Keith Urban.

“That’s my baby,” Kidman said, passing over the black and white image that showed mother and daughter asleep, their heads touching.

“Oh, (she’s) so much like Keith – I call her Keithette.”

Kidman and Hugh Jackman – stars of the upcoming Baz Luhrmann’s epic, Australia – appeared on Monday’s Oprah show, with the set fitted out to look like a 1930s outback cattle station where Australia is set.

Oprah gushed about the film, an endorsement sure to give the film a huge boost in the US, where it opens later this month.

“Congratulations on your imagination, your vision, your creativity, your direction. Our hearts are all swelling because, my God, it’s just the film we needed to see,” Winfrey told Luhrmann, who appeared via a cross from Sydney.

Kidman said she said agreed to do the film without even seeing the script.

“He (Luhrmann) just called me up and said: ‘I’m thinking about this film’. And I’m like: ‘I’m in. I’m yours’, because I feel also that there are directors that bring out something in you that nobody else brings out,” she told Winfrey.

Jackman said she convinced him to do the same.

“I said: ‘Well, tell me what the script’s like because Baz wouldn’t really tell me much about it’. And she said: ‘Oh, I haven’t read the script. You just sign on’. And I said: ‘You haven’t read the script?’ She goes: ‘No, this is Baz Luhrmann. Just do it’,” Jackman said.

Luhrmann is still putting the finishing touches to the film, due to premiere in Sydney next Tuesday.

“At the end of the day, all you’ve got is your story, so try to make it a good one,” he said, quoting a line from Australia.

“Hugh and Nicole and I, we’ve been on an incredible story and a journey, and if it can put a little bit of good spirit and hope and joy out in the world at this time, then it’s been worthwhile.”

Jackman managed to win Winfrey and the audience over with packets of Tim Tams.

“You think it’s hard getting through customs with nail scissors? Try getting through with over 300 packages of Tim Tams,” Jackman said.

It was enough for Winfrey to start speaking another language.

“You call cookies bikkies there? We’re gonna start calling them bikkies too.”
