Nicole Kidman is giving a whole new meaning to the expression "There must be something in the water."
The 41-year-old Oscar winner, who welcomed daughter Sunday Rose in July, believes swimming in the "fertility waters" of the Australian Outback during production of her upcoming film, Australia, may have contributed to her conceiving.
"I never thought that I would get pregnant and give birth to a child, but it happened on this movie," Kidman tells the Australian Women's Weekly, adding that six other women who also went for a dip soon began sporting baby bumps as well.
"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."
