Holly Willoughby was left mortified today after she revealed a key detail about chef Clodagh McKenna's wedding.
Holly and her co-host Phillip Schofield were enjoying Clodagh's elderflower and lemon drizzle cake when Holly made the slip-up.
The mum-of-three said: "This is so good and you like this cake so much that you had it in your wedding."
Clodagh looked shocked at Holly's comment and said: "Well it's going to be in my wedding cake in August, but I wasn't going to tell anybody."
Holly slapped her hand across her mouth and said: "Oh".
Phil put his head into his hands as Clodagh laughed and said: "No don't be silly.
"No it's not that big a deal, I want to give you a hug but I can't.
"It's not that big a deal, it is going to be when I get married in August."
Holly said: "You said it earlier to me and I just thought that you were...."
Phil turned to Holly and said: "What word just came into your head then."
And Holly replied: "What she said...." in reference to Clodagh's earlier bad language on the show.
Viewers were quick to pick up on the incident, with many of them commenting on it on social media.
