Good Morning Britain viewers tuned in to see Susanna Reid, 47, and Adil Ray, 44 host the show.
As they crossed over to the weather, delivered by Laura, 37, who was live from Chessington, she was given the shock of her life.
‚ÄúGood Morning, I have a special friend with me here,‚ÄĚ as she stood holding a skeleton figure.
‚ÄúThis is Jon bone-Jovi, see what I did there?‚ÄĚ
‚ÄúAnd I thought, as it‚Äôs Halloween, I thought we should tell a skeleton joke‚Ä¶‚ÄĚ¬†
Viewers then saw someone running from the back of the castle, up to Laura dressed as a zombie, complete with scary face paint.¬†
Screaming she tried to run away, but the zombie followed making gruelling noises.¬†
‚ÄúOh god. I don‚Äôt know what‚Äôs happening,‚ÄĚ Laura squealed. ‚ÄúOh god, ok.‚ÄĚ¬†
Following the hilarious moment, Laura took to her Twitter account and shared a photo alongside the zombie.¬†
‚ÄúOMG! That gave me the fright of my life! I just heart feet running!! My heart was racing & I don‚Äôt remember a word I said!
‚ÄúThanks producer Michelle! @shelly284 @GMB‚ÄĚ it read.¬†
Those watching at home took to Twitter to discuss the hilarious moment.¬†
One said: ‚Äú@GMB This was hilarious this morning, poor @Lauratobin1 got such a fright. Happy Halloween!‚ÄĚ¬†
‚Äú@lauratobin1 @GMB very funny it‚Äôs as well you didn‚Äôt curse because I know I would have!‚ÄĚ Another added.¬†
A third wrote: ‚Äú@lauratobin1 @GMBThat‚Äôs actually quite terrifying at something past six in the morning.‚ÄĚ
It comes after yesterday‚Äôs show when Chancellor Phillip Hammond joined the hosts.¬†
Speaking about the recent budget, Susanna questioned Phillip on his potential next move within the party.¬†
She tried to offer the Chancellor a mug which said ‚ÄėPhillip Hammond Prime Minister‚Äô written on it and viewers saw him flatly refuse the mug or position.¬†
‚ÄúHands it straight back. Couldn‚Äôt be any clearer,‚ÄĚ Susanna joked.
Good Morning Britain airs weekday mornings at 6am on ITV.¬†
