Granny Freeze revealed in an interview with The Australian Women's Weekly that she conceived Sunday Rose after wading around in the waters of a small town in the Outback called Kununurra.

"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."

Granny also tried to explain why her bump was so tiny during her pregnancy – at times barely noticeable at all.

"I'm so lucky I'm so tall, so I carried small. Also, I have to say, I had a birth that I was blessed with, a labor that was very good and a baby that was very good to me in that regard.”

Just for fun, I’m attaching a few of her pregnancy pics. Working out in June (wearing black) just a month before Sunday Rose’s arrival…

This is what I look like after a big rib dinner. Gran? Gran’s 8 months along!

And another photo of Granny in a pink silk blouse in March … not much difference.

Must be the height. Totally.
