Giuliana and Bill Rancic are having a baby

After years of struggling to conceive, Giuliana and Bill Rancic are finally expecting!

The E! News host and her husband announced Monday on the "Today" show that they’re going to become parents via a gestational surrogate.

The pair, who star on the Style network reality show “Giuliana & Bill," have been open about their journey to parenthood, which has included a miscarriage and ineffective IVF treatments.

Now the couple say they’re expecting their bundle of joy with the help of a gestational surrogate, which means the child is biologically theirs and is being carried in another womb.

"It was pretty much one of the best moments of my life, if not the best moment of my life," Giuliana said on the morning show, explaining that they’d discovered one of the embryos she’d banked prior to learning she had breast cancer had proven successful.

"It was just another world, on another level,” she said, adding that she and Bill know the sex of the child but are saving it as a surprise.

"This was our last stop," Bill added. "This was it. We had those two embryos that we had banked prior to learning about the breast cancer, and with the medicine she was on, this was our last effort. The prayers were answered."

The woman carrying the baby, who Giuliana joked is her “baby mama," lives "out of state" and is married with two kids of her own. She's due in late summer.
