Nicole Kidman's baby tears

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.

She added to America's Vogue magazine: "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.' "
