Urban told reporters of the baby on the way, "We're very excited."
Added wife Kidman, "We're very pregnant and good."
According to Now Magazine Online, UK: Nicole Kidman wowed fans on the red carpet on Sunday when she showed off her big baby bump.
The actress, who is nearly 7 months pregnant, has always been super slim.
But as she arrived at the 43rd Annual Academy of Country Music Awards with husband Keith Urban she was happy to flaunt her curvy figure.
Wearing a strapless silver dress, Nicole stroked her stomach and cuddled up to Keith, 40, as they laughed and joked in front of the crowds.
And Nicole, 40, is said to be so proud of her voluptuous body that she's asked celebrity snapper Patrick Demarchelier to photograph her in the later stages of pregnancy.
Nicole is due to give birth in July.
She is already mum to adopted kids Isabella, 14, and Connor, 12, with ex husband Tom Cruise, 45.
