Nicole KidmanWe're glad it's nearly winter so we don't have to go swimming soon.

Not after what happened to Nicole Kidman.

After her last dip, she fell pregnant.

But let us explain a tad more.

Chatting to The Australian Women's Weekly, she's explained how during the filming of new movie Australia she and six other women who swam in waterfalls near a small Outback town all fell pregnant.

She said: "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."

She also revealed details of her pregnancy, saying: "I'm so lucky I'm so tall, so I carried small and also, I have to say, I had a birth that I was blessed with, a labour that was very good and a baby that was very good to me in that regard.

"To be given this again is a beautiful thing. To have raised Bella and Connor (her adopted children with Tom Cruise) since I was 25 and now to be able to do it again at 41, wow."

Nic and hubby Keith Urban welcomed their daughter, Sunday Rose, into the world in July this year.
