Sydney - Australia's acclaimed film director, Baz Luhrmann, and Oscar-winning actress Nicole Kidman may never team up again following the completion of the epic outback movie Australia, media reports said Wednesday.

"We both said we can't make another movie together because there are only so many life-transforming events we can go through," Luhrmann told Britain's Daily Telegraph newspaper.

When filming Moulin Rouge, Kidman, 41, was breaking up with then-husband Tom Cruise and Luhrmann's father died on the first day of filming,

"Then six weeks before we finished filming Australia we were doing a scene where her character has to say she can't have children and she goes, 'Bazzy, Bazzy, I've got to see you,' and we sit down under a tree and she tells me she's pregnant and she burst into tears and I did, too, because I knew that was what she wanted more than anything else," Luhrmann told the newspaper.

Meanwhile, the film Australia, also starring Hugh Jackman, has received mixed reviews from critics across the world, many of them critical of Kidman's performance.

On Tuesday, Kidman earned the wrath of Aboriginal Australians when she appeared on a popular German television chat show blowing into a didgeridoo, the traditional instrument of indigenous Australians, to promote her new film.

According to Aboriginal tradition, women are not supposed to play the didgeridoo as it could make them infertile.

"People are going to see Nicole playing it and think it's all right. But it will mean she has no more children. It is not meant to be played by women as it will make them barren," Aboriginal language teacher Richard Green told local media. (dpa)
