As Nicole Kidman and Keith Urban, both 40, near the July birth of their first baby, friends tell OK! that the pair can barely contain their excitement.

Their joy was obvious at the 2008 Academy of Country Music Awards, when it was all Nicole could do to keep from caressing her bulging baby bump while posing with Keith on the red carpet.

While Nicole has some experience with children (she's got two adopted kids with ex Tom Cruise), this will be Urban's first time at fatherhood. His former manager and author of Make Me a Star, Anastasia Brown tells OK!, "He is so sweet to children. He'll be a perfect pop."

Brown has equally nice words for Nicole, saying the Oscar winner is "so funny, just awesome."
