However she quickly went on to introduce her I’m A Celebrity… Get Me Out Of Here! alum John Barrowman MBE.
John barged onto the set screaming his signature: “Fabulous!” causing Holly to scream with delight.
But John had a trick up his sleeve as he brought out his hand from his pocket.
In a fell swoop he brought out a group of fake spiders and flung them at his co-host.
Startled, Holly yelled: “Oh my god you idiot!
“What are you doing!?”
Trying to explain his actions through laughter, John said: “I brought a little something from the jungle!”
Once they had calmed down Holly and John settled down and began the show.
But fans were utterly elated by the prankster’s actions as they began speaking out on Twitter.
One fan wrote: “Watching #ThisMorning with #johnbarrowman presenting. It is as he sings fabulous and inspirational and cheerful!!!!”
Another said: “ThisMorning John Barrowman on today’s episode. Fabuuuuuulous.”
While a third chimed in: “Aaahhh! #ThisMorning with @JohnBarrowman presenting with @hollywills SO EXCITED!”
Meanwhile other viewers called for John to stay on the show permanently.
One said: “Ok can we have John, Phil & Holly hosting all together please and thank you! John suits this role! #ThisMorning.”
And the pranks didn’t stop there, as John continued to pull out more spiders throughout the show.
Luckily for Holly, John was mostly well-behaved the rest of the day.
This Morning also saw the pair talk to Emma Fairweather discussing her recent car crash with Prince Philip.
During the interview Emma said: “I need somebody to understand that I still have medical concerns.”
This Morning airs weekdays at 10.30am on ITV.
