Giuliana and Bill Rancic Speak on Surrogate

Giuliana and Bill Rancic, who have opened up about their struggle to have a child in the last few years, announced Monday that they're finally expecting a baby.

They've bonded with the woman who is making it happen, too.

"She is giving us the greatest gift we're ever getting in our lives," Giuliana, 37, says of the couple's surrogate, whose identity has not been revealed.

"She's selflessly helping make our dream a reality. We adore her."

The gestational surrogate is carrying their child, but it will be their biological offspring. Giuliana's struggles to achieve a viable pregnancy are well documented.

Asked if they plan to stay in touch with the woman once their child is born, Bill says, "That will be up to her, but we are very grateful for what she's done."

"We intend to maintain a relationship with her."

The couple admit they were quite nervous about picking a surrogate before they met the woman they chose, but they clicked with her immediately.

"Once we met her it was an instinct," says Giuliana. "We could tell she was a great person." Bill adds that the Rancics attend her doctor's appointments:

"It's important to us to see the development and growth. At the end of the day, it's our baby. Genetically it's ours. It's our embryo. We feel very connected."

For now the parents-to-be are relishing keeping the baby's gender a secret – but they know, and may not be able to keep it for the duration of the pregnancy.

"When you do a reality show and host shows, it's hard to have secrets. Its nice to have something that only the two of us know for now," says Giuliana.

However, "Eventually we may tell people."
