Kidman tells the Australian Women’s Weekly that she believed she got pregnant by swimming in some “magic waters” in Australia where she filmed her latest movie. Apparently seven other women who worked on the film and also swam in the water got pregnant too. She says,

I never thought that I would get pregnant and give birth to a child, but it happened on this movie. Seven babies were conceived out of this film and only one was a boy. There is something up there in the Kununurra water because we all went swimming in the waterfalls, so we can call it the fertility waters now.
