E! News host Giuliana Rancic and her husband Bill have revealed that they are expecting their first child via a gestational surrogate.

The 37-year-old presenter, who has suffered one miscarriage and a diagnosis of breast cancer, announced on Monday on the Today show that the couple will soon have another addition to their family.

An ecstatic Giuliana said: "We are so thrilled that our prayers have been answered. It was one of the best moments of my life, if not the best moment of my life."

"It's incredible. We've been trying for so long, we've been through so much...And to finally get that call from the doctor, it was just another world, another level," the Fashion Police cohost added.

Her husband also expressed his joy at the news by saying: "We are absolutely ecstatic to be sharing this with everyone who has been following our journey."

The baby, who is being carried by an unnamed woman but is genetically the Rancics, is due in late summer.

However, the couple are keeping tight-lipped about the sex of the child, "We're seeing how long we can keep it secret," Giuliana admitted.

They couple, who have been married for 2007, have made no secret of their desire to become parents.

Their wish to have children contributed to Rancic's decision to undergo a double mastectomy in December following her breast cancer diagnosis.
