Rochelle Humes made a raunchy joke about King Charles' bedroom performance on This Morning.
Rochelle and Craig Doyle helmed the ITV daytime show instead of regular hosts Holly Willoughby and Phillip Schofield.
The hosts were chatting all things royal as they discussed today's news with guests Gyles Bandreth and Camilla Tominey, following King Charles' Coronation on Saturday.
Rochelle then turned to a survey in which stamp collectors rated themselves as the best lovers.
Celebrity Gogglebox star Gyles then said: "I am able to reveal to you that the new king, King Charles III, has the finest stamp collection in the world."
Rochelle then joked: "You know what that means."
Going on, Gyles said: "Which he inherited from his mother who inherited it from her grandfather. King George V, he had two great passions, one we won't talk about, shooting birds, he shot grouse and pheasants like there was no tomorrow, and for them there wasn't.
"But his happier hobby was collecting stamps. He built personally, putting them in his stamp album, the finest collection of stamps in the world."
The foursome then pointed out the survey, which also received responses from metal detectorists, didn't hear from the stamp collectors' partners, casting doubt on how accurate it could be.
While Holly and Phil missed out on dissecting all things royal on This Morning, Holly did get into the patriotic spirit.
The presenter showed off her impressive baking skills ahead of her Coronation celebrations.
Holly wowed her fans with her hidden talent, which took her two days to complete.
She admitted she "can't wait" to have a slice of the giant crown-shaped cake but is resisting until the big day tomorrow.
Holly looked overjoyed with her creation as she posted a snap on her Instagram.
Going with the patriotic theme by wearing a red T-shirt and blue jeans, she beamed as she held up the impressive cake for fans to see.
Holly wrote alongside the pic: "Well @julietsear and @thismorning I did it!!! Started it last night and just finished… don’t look too closely…
"It may not be perfect but I can’t wait to have a slice with the kids and a glass of bubbles whilst watching the Coronation tomorrow … whatever and wherever you are this weekend enjoy the moment and I hope the cake is involved somewhere!"
The cake was shaped like a crown, with large edible jewels attached and white frosting for the fur.
Holly was flooded with comments from impressed celeb pals.
Baking expert Juliet Sear said: "Holly this EPIC!!! SO COOL you nailed this! [clapping hands emoji] Well done and have a brilliant bank holiday weekend xxx."
Love Islander Laura Anderson wrote: " Awww superb looks royally delicious."
Clodagh McKenna Herbert, who appears on This Morning during cooking segments, added: "WOW!! That is SO impressive!!!"
"Brilliant! I stuffed a slice of Juliet’s yesterday and it was delish!," commented Alice Beer.
