The couple are about to become first time parents via gestational surrogate and they can't wait. Bill Tweeted, "On the plane to Denver!! Baby watch has officially started!!"
After battling breast cancer, a heartbreaking miscarriage, and infertility issues, the reality stars' dream of having a family is finally happening and Giuliana is "over the moon," Bill said.
The baby will be born in Colorado, which is where the woman who is carrying their child lives.
"We're going to go from Colorado to Chicago and then spend September and October in Chicago. And then we'll come back to the West Coast," Bill explained to Us.
The soon-to-be parents will take their son home to the Midwest in style and have planned quite the road trip. "I've got a tour bus taking us from Denver to Chicago," Bill said.
"Everyone is pumped!" he added. "Not just our family but so many people. We're so lucky. So many people have been pulling for us and following our journey. This has all been magical for us."
