Viewers were left in hysterics as Cat Deeley made a hilarious appearance on Saturday Night Takeaway, where she reunited with her former SMTV: Live co-stars Ant and Dec.

Ready to take her ‘revenge’ on the pair after their brutal prank years earlier, the new This Morning presenter, 47, announced that she was going to read a dreadful bedtime story.

Teasing that the hosting duo had ‘no idea’ what she’d prepared for them, the presenter left the public and audience at home in stitches after branding Newcastle as ‘dark and dreary’.

Cat made a glamorous entrance in a black beaded mini dress with one sleeve off and one puffed sleeve, while holding the ‘dreadime story’ book in her hands.

Ant and Dec were then forced to dress up as their hilarious monster alter-egos Anty and Decky, and then the duo brought to life everything Cat said while narrating the story.

While Ant donned a purple hairy cyclops, Dec also become a brown hairy monster with quirky orange hair.

And as the This Morning star went on with her frightening plot, the hosting pair suffered a hilarious ‘electric shock’ to their bum – leaving the audience to burst into uncontainable laughs.

‘Suddenly, the weather took a nasty turn. It can be like that in dark and dingy Newcastle, and poor Anty and Decky got struck by lightning,’ she said pressing a button next to her.

Terrified Decky exclaimed begging: ‘Cat, no, don’t press that!,’ before another lightning strike hit them once again.

‘And they say lightning never strikes twice but sadly, for Anty and Decky tonight it did,’ Cat went on pressing the dreadful button for a third time.

But there was more to it, as even Cat’s fellow This Morning’s co-host Ben Shephard also made a hilarious appearance as part of the prank.

The former Good Morning Britain star, 49, was seen inside a box holding some fake birds leaving fans cracking up at the funny scenario.

Viewers were in hysterics, with some gushing over the Cat, Ant and Dec reunion and recalling the 1998’s legendary sketch comedy SMTV Live on ITV, which featured the trio hosting together.
