Fans of This Morning were shocked when Holly Willoughby accidentally told a sex story live on TV.

Holly and Ben Shephard, the show’s hosts, talked with guests Vanessa Feltz and Matthew Wright on their ITV show.

They looked into the interesting fact that the most babies are born on this particular day. They think that this is because couples get romantic during the holidays, which causes them to have babies in September.

Holly said right away, “The heating hadn’t gone on that winter,” and then she made a joke. Ben said, “Happy Birthday to Chester. He’ll be thrilled we are talking about Christmas,” which made everyone laugh.

Matthew asked Holly if it was true, and she joked, “I couldn’t possible say.” Since Chester was born on Friday, Holly and her husband Dan Baldwin probably got pregnant around Christmas.

This year, Holly told a rare story about how she and Dan met and how they were just friends at first.

It comes after guest Miriam Margolyes caused chaos on This Morning by talking about her sexual life and swearing twice on air.

Holly Willoughby got red in the face and had to apologize to fans after the outspoken actress, 82, mouthed an expletive and then said “s**t” on the phone-in show.
