Giuliana Rancic's husband has revealed their surrogate recently miscarried their second child.

Bill Rancic, 43, admits he and the E! News anchor - who have documented their fertility struggles on their self-titled reality TV series - ''were devastated'' when they found out a woman Delphine, who also gave birth to their 21-month-old son Duke, lost their unborn baby at nine weeks.

The entrepreneur told ''This whole season on 'Giuliana and Bill' we've been trying to have another baby.

''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.''

Giuliana, 39, took the news particularly badly and was ''distraught,'' according to Bill, but they still hope to have more children in the future.

He said: ''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.''
