"This whole season on Giuliana and Bill we've been trying to have another baby," Bill told People of the couple's reality show. "Unfortunately our surrogate Delphine, who we love very much, had a miscarriage. It's something we didn't see coming. We were devastated."

He continued, "She was about nine weeks pregnant. We were pretty close to getting into the safe zone. We experienced a miscarriage years ago when we were trying with Giuliana, so we had been keeping the pregnancy news tight to the vest."
Giuliana, 39, and Bill have not faced an easy road to parenthood. It was during the E! News host's attempts to get pregnant using in-vitro treatments that she was also diagnosed with breast cancer, and underwent a double mastectomy. Their son Duke, 21-months, was born via gestational surrogate in August 2012.
"Delphine is amazing. We hit the surrogate lottery when we met her," Apprentice winner Bill, 43, said. "Obviously this was no fault of hers.

"It's a double sadness because we didn't want her to feel bad. And Giuliana was rather distraught at first, but she's tough. In times like this we rely on our faith. Once the tears went away we started to look towards the future."
He added that the couple are not giving up on their dream of having another baby.
"We're fighters. Hopefully we're going to have good news and Delphine will be on board one more time. We've had to battle it out and that's something that we're going to continue to do."
