Bill and Giuliana Rancic recently welcomed a baby via surrogate, and they've kept the woman's identity a secret -- until now.

In a clip released by Style to promote the season premiere of couple's reality show, Giuliana & Bill, the surrogate is revealed to be a woman named Delphine. She is seen accompanying the couple as they tour the Denver hospital where she would give birth to their son, named Edward Duke, on Aug. 29.

The Rancics have documented their difficulties getting pregnant on their reality show; Giuliana struggled with IVF treatments and had a devastating miscarriage. In April, when they announced they were expecting, Giuliana called the surrogate -- whom they found through their Colorado-based fertility doctor -- "a dream come true," without sharing her identity.

The co-host of E! News and the network's Fashion Police revealed her breast cancer diagnosis on the Today show in October, returning to work two months later after undergoing a double mastectomy.

"Bill and I are blessed beyond words to welcome Edward into our lives," Giuliana told E! News after the birth of the baby, who weighed in at 7 pounds, 4 ounces. "Thank you so much to everyone who supported us along the way. We are so in love with the little guy already!"
