Nicole Kidman and her husband of one and a half years, country singer Keith Urban, are happily expecting their first child together, her representative has confirmed.

People magazine reports on its website that Nicole Kidman’s rep has confirmed the latest round of rumors concerning the actress’s pregnancy. While impending motherhood has been persistently attributed to Nicole since her marriage to Keith (consistently followed by denials from her camp), this time around the scrutiny of Nicole’s waist has been rewarded with good news.

“The couple are thrilled,” her rep Catherine Olim said in a statement.

Nicole, 40, already has two children she and actor Tom Cruise adopted during their 10-year marriage. Isabella is 15, while Connor is 12.

For Keith, 40, this will be the first baby.

The Academy Award winning actress and the Grammy Award winning singer married in June 2006, having begun their romantic relationship a year earlier. Nicole has been open about her desire to have a child for a long time now.

In an endearingly straightforward interview which appeared in last year’s October edition of Vanity Fair, the 40-year-old confessed that she had wanted to have babies from the very beginning of her marriage to former husband Tom Cruise. The two wed in 1990.

“From the minute Tom and I were married, I wanted to have babies,” the Australian actress says. “And we lost a baby early on, so that was really very traumatic. And that's when it came that we would adopt Bella.”

The couple adopted Isabella in 1992 and Connor in 1995.

The two children now shuttle between their mother’s place and their father’s, who has in the meantime married Katie Holmes, with whom he has daughter Suri. Also last year, she told Marie Claire in its December issue that Isabella and Connor tend to spend more time with their father in L. A.

“When children are teenagers, they have a say in where they want to be. L.A. is a big draw, and I'm looking to get a place there so we can share more.”

In addition, Nicole told Vanity Fair that she had not given up her hope to have a biological child. “I'm yearning to have one. I think I would be very sad if I wasn't able to have a baby. Keith knows I want one, and he has been getting there slowly.”
