Holly Willoughby said it was ‘horrible’ having to keep her pregnancy secret from the world.

The This Morning presenter – who tweeted the good news last Friday – spoke for the first time about the pregnancy on the show yesterday.

The 33-year-old already has two children with her TV producer husband, Dan Baldwin – four-year-old Harry and two-year-old Belle.

Talking to co-host Christine Bleakley, Holly explained that her oldest child is over the moon to meet his new brother or sister.

“When Belle came along, Harry was not even two yet, so he didn’t really get it,” she said. “This time he gets it and he came downstairs, and I was just waking up, and he went, ‘I just wanted to come down and make sure you and the baby are OK.’ It melts your heart! It’s all lovely.”

Holly also spoke of the relief at finally being able to tell everyone the good news.

“That first bit when you can’t say anything to anybody, it’s horrible because you just want to go ‘I’m pregnant!’ Now it’s nice that everybody knows and it’s out there,” she told her Bleakley.

Holly and Dan have decided not to find out the baby’s sex before the birth.

“I’m not going to this time,” she announced on the show. “I found out with Belle, but this time we’re not going to find out.”
