Nicole Kidman started crying the first time she saw her baby on an ultrasound machine.

The "Moulin Rouge" actress -- who is expecting her first biological child with husband Keith Urban -- was so overwhelmed with joy when she saw the image, she couldn't hold back the tears.

She said: "When I first saw the baby on the ultrasound, I started crying. I didn't think I'd get to experience that in my lifetime. I like the unpredictable nature of it. "To feel life growing with you is something very, very special, and I'm going to embrace that completely. I don't believe in flittering around the edges of things. You're either going to walk through life and experience it fully or you're going to be a voyeur. And I'm not a voyeur."

Nicole also revealed she loves all aspects of being pregnant.

"The whole experience is so primal. But I'm glad I've learned to let things flow. I'm now so much more capable of receiving love and giving it in a far different way. So to be given the blessing of a child at this stage of my life, you just say, 'Wow, this was meant to be.' " she said.
