Nicole Kidman ensured that all eyes were on her sizable baby bump at the 43rd Academy of Country Music Awards in Las Vegas at the weekend.

The mother-to-be was there to support her singer husband, Keith Urban, and made sure to use a strategically-placed hand beneath her stomach to emphasis her tummy to full affect.

Dressed in a flowing satin gown, Kidman looked relaxed and happy as she playfully hugged Urban on the red carpet.

The actress – believed to be seven-months pregnant with her first biological child – has been a bit of a late-bloomer in the bump stakes.

Only a few weeks ago, you would have been hard pressed to tell that she was pregnant at all.

Kidman has said of being pregnant, "I'm so happy. I can't ask for anything more...except big boobs."

It looks like that wish is coming along nicely too.
