Nicole Kidman has revealed that she believes swimming in fertile waterfalls in the Australian Outback helped her become pregnant.

The actress and husband Keith Urban welcomed daughter Sunday Rose in July.

She told Australian Women's Weekly that she and six other women swam in the waterfall while filming new epic Australia and now call the pool "the fertility waters".

"I never thought that I would get pregnant and give birth to a child, but it happened on this movie," she said.

"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."

Kidman and Urban were spotted attending a football match in the UK last weekend.
