The ITV hosting duo were crying with laughter as they had to do take after take for the short promo, which was filmed after the programme on Tuesday, because they kept cracking up.
This Morning shared a three-minute video of Holly, 35, and Phil, 54, in the brilliant blooper reel that showed them struggling with the item.
At the start of the footage Phil was heard telling the audience: “Just cut that together! The impossible nature of attempting to try to record a promo for tomorrow’s show with the words ‘Gywneth Paltrow’s pantry’ in it!”

Phil had his face in his hands and wiped away tears, saying: “It doesn’t matter how much you change it, there’s nothing you can do! How we’re going to do it tomorrow, I do not know.”
Holly quipped: “You’re going to have to bleep out a lot of that as well.”
They were then seen doing another take, which went well until the very end when Phil burst out laughing.

“We’re going to have to swap it around, I can’t do it!” he told Holly as he was bent over in stitches, before adding: “Swap it around, I can’t do it!”
Neither Phil nor Holly could contain themselves and filming had to be halted temporarily. Even the crew were heard laughing in the studio from behind the camera as they watched the two.
Another take saw Phil interrupting Holly, causing her to tell him: “You’re so desperate to get your bit done!” She warned him: “One more and I’m doing it by myself!”
