Joined by St Patrick's Day co-presenter Christine Bleakley, who quickly offered her congratulations, Holly admitted it had been hard to keep a lid on the announcement.
"That first bit when you can't say anything to anybody is horrible, because you just want to go: 'I'm pregnant!'" she smiled.
"But now it's nice that everyone knows and it's out there."
Holly also revealed that it had been lovely telling her two children, Harry and Belle, about their future little brother or sister.
"Obviously when Belle came along, Harry was not even two yet, so he didn't really get it. But this time, he really gets it," she said.
"This morning, he came downstairs and I was sort of just waking up and he went: 'I just wanted to check you and the baby were okay ...' Melts your heart!"
Meanwhile, This Morning was all about the girl power again after Christine's previous stints on the show, as she was joining Holly to cover for Phillip Schofield while he filmed Mr And Mrs.
And he took to Twitter with one little warning for the ladies - not to be too good in his absence!
