The star is seen sporting a bump at the American Music Awards
Usually svelte star Nicole Kidman was sporting a definite bump as she posed on the red carpet at the American Music Awards.
The actress looked glowing with health and suited the fuller figure, which has set tongues wagging in Hollywood.
Pictures show Nicole cradling her small bump, then holding a finger up to her lips for waiting photographers.
Definitely keeping something a secret then!
The superstar actress already has daughter Sunday Rose with rocker husband Keith Urban, and pictures have shown the proud parents looking blissfully happy with their small addition to the family.
So could there now be a sibling on the way to complete the picture?
