Giuliana and Bill Rancic reveal identity of surrogate mother in their reality show promo

Giuliana and Bill Rancic are revealing the identity of the surrogate mother who helped them bring their son into the world.

A clip from the couple’s reality show Giuliana & Bill shows the mom and dad-to-be being coached in the delivery room with their surrogate, Delphine.

Delphine, who carried the Rancic’s son Edward Duke to term, is seen with the couple and a hospital worker who talks them through the process of what will happen the day of delivery.

While Giuliana and Bill Rancic bicker over who will first get to hold the child, and who will cut the umbilical cord, Delphine seemed at ease and open to letting the pair be as much a part of the process as possible.

Delphine eventually gave birth at a Denver, Colorado hospital on August 29 with the Rancics by her side.

Edward Duke Rancic was born at 10:12 p.m. and the baby’s umbilical called was cut by Giuliana and Bill moments before they held him ahead of anyone else.

The couple named the tot after Bill Rancic’s father, who was called Edward, and Giuliana’s dad, Eduardo.

The American entrepreneur and reality star tweeted the news of the then-anonymous surrogate going into labor.

“It’s game time,” Bill Rancic posted on his Twitter account.

After little Edward was born, the couple said they felt “blessed beyond words” to have become parents for the first time.

Giuliana Rancic, 37, took to Twitter, writing: “It’s true what they say (and what u all told us)…. @BillRancic and I couldn’t love little Duke anymore than we do. He’s a dream….”

Bill Rancic, 41, tweeted: “The <<Duke>> has landed! Edward Duke Rancic was welcomed into the world last night at 7 lbs 4 oz. G& I feel blessed beyond words…We did it!(sic).”

The happy arrival came after Bill Rancic and his E! News host wife struggled to conceive naturally, undergoing three failed cycles of IVF.

Then last year during her treatment Giuliana Rancic was diagnosed with breast cancer, putting their dreams of a family on hold.

She underwent a lumpectomy followed by radiation before undergoing a double mastectomy.

Following her recovery the couple decided to use a surrogate to try for a baby, and they were thrilled when their attempt ended in a pregnancy.

Bill Rancic earlier this year opened up about the journey, telling the TODAY show how he and his wife “hit the gestational carrier lottery”.

Presenter Giuliana Rancic, meanwhile told E! News: “Bill and I are blessed beyond words to welcome Edward into our lives.

“Thank you so much to everyone who supported us along the way. We are so in love with the little guy already!”

Giuliana & Bill is scheduled to premiere on the STYLE network on October 2 at 8:00 p.m. EST.
