"We've got the pregnancy test," the couple's fertility specialist, Dr. William Schoolcraft, tells the Rancics while on the phone with their gestational carrier, in a Style Network clip.
"It's completely 100 percent positive. She's carrying a baby. Everything went as well as I could have dreamed."
"Oh my God," Giuliana responds, crying as Bill's eyes fill with tears. "Thank you. We're so happy – thank you so much."
The couple will welcome their first child in late summer. They know the sex of the baby, but are "seeing how long" they can keep it a secret.
