Nicole KidmanNicole KidmanSo here it is.

The photo that sparked a thousand pregnancy rumours.

Nicole Kidman has said she definitely ain't up the duff, but this snap of her tum is the one guilty of making a million tongues wag from Oz to Hollywood to the UK and beyond.

Nic's spokesman categorically denied the baby type rumours earlier this week, telling the Melbourne Herald Sun:

"It is incorrect. She (Nicole) must have had about 30 babies by now.

"It's the silly season. As far as we're concerned it's another rumour out of London."

But in case you were wondering, this close-up of Nic's stomach covered by a floaty dress is where it all started.

This is what had gossip queens abound speculating that Nic and her husband, Keith Urban, have a bun in the oven.

Leading to the above denial on Nic's behalf.

So now you know.
