The This Morning co-host wrapped up warm in a pale pink coat and embellished green jumper, meaning any hint of a baby bump was firmly out of sight!
33-year-old Holly announced her third pregnancy last week, saying that she and TV producer husband Dan Baldwin are thrilled to be adding to their family.
They're already parents to son Harry, four, and daughter Belle, two.
Holly was joined at the taping by close friend and Celebrity Juice co-panellist Fearne Cotton, who was one of the first to send congratulations to her on the baby news.
Fearne tweeted: Soooo happy for @hollywills."
Holly spoke about her pregnancy on This Morning earlier this week, revealing that she's decided not to learn the baby's sex before the birth.
She added that telling her children of the pregnancy had been a fantastic moment.
"When Belle came along Harry was not even two so he didn't really get it, but this time he really gets it and this morning he came downstairs and I was just waking up and he went, 'I just wanted to make sure you and the baby were OK'.
"It melts your heart. It's all lovely."
