Nicole Kidman is giving new meaning to the expression “there is something in the water.”

41year-old Kidman claims that swimming in the “fertility water” of the Australian Outback during the production of the 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.”
