The Fashion Police star and husband Bill Rancic announced in April that they are expecting their first child via a gestational surrogate after having difficulties conceiving on their own.
"The baby is due the end of August, and I wrap at the Olympics [in London] on August 11. So we are going to be on standby," Giuliana explained on the Today show.
"We think it's going to be okay. The doctor assured us. He thinks maybe even early September the baby will come."
She went on to confess that Bill is more than excited to be welcoming a little boy, saying: "It was funny because I told Bill, 'You realise you can't play ball with him for a while?'
"I think he thinks at 6 months they're going to be playing catch. I'm like, 'Honey, that doesn't happen for a little while'. He's like, 'I was waterskiing at 3 years old'. I'm like, 'Slow down, honey!'"
