Giuliana and Bill Rancic revealed Sunday that their surrogate has suffered a miscarriage.
"This whole season on 'Giuliana and Bill' we've been trying to have another baby," Bill told People about their E! reality show. "Unfortunately our surrogate Delphine who we love very much had a miscarriage. It's something that we didn't see coming. We were devastated."
He added, "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."
Bill, 43, and Giuliana, 39, welcomed son, Duke, via surrogate in August 2012.
And from the sound of it, they're planning to try again: "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."
The couple hasn't been shy about their challenges getting pregnant, documenting a lot of it on their reality show. Giuliana, who has also battled breast cancer, underwent multiple in vitro treatments as well.
