Giuliana Rancic is one step closer to having the baby that she and husband Bill Rancic have always dreamed about.
The E! News host and Fashion Police
cohost, 37, whose road to motherhood has been made difficult by infertility struggles
, one miscarriage
and a diagnosis of breast cancer,
announced in person Monday on the Today
show that she is expecting.
"We are so thrilled that our prayers have been answered," Giuliana tells E! News
. Adds Bill, 40, "We are absolutely ecstatic to be sharing this with everyone who has been following our journey."
The child is due in late summer via a gestational carrier, meaning that the Rancics will be the genetic parents. They know the sex of the child, "but we're seeing how long we can keep it secret," Giuliana said on Today
She aded that the surrogate mother lives out of state, but that they accompany her on all the visits to the doctor.
The couple's desire to have children played a part in Rancic's decision in December to undergo a double mastectomy.
The years of medication that typically follow a lumpectomy and radiation therapy would have meant delaying parenthood for several more years.
At the time, Rancic said she was crushed by her 2010 miscarriage. "I said, 'I'm not doing this again. I can't.' I was angry at life and at God," she admitted. But the couple decided to press on again with in vitro fertilization.
Each step of their lives has played out quite publicly, in part because it's all documented on their Style Network reality show, Giuliana & Bill
, currently in its fifth season.
