Saturday Night Takeaway viewers are obsessing over Dorothy's return in the final episode of the ITV series. 

Avid fans of the show will remember Dorothy from earlier in the series where she won the nation's hearts during Ant and Dec's security prank.

We all enjoyed watching the clueless participants jump through hoops on 'Takeaway Security' as the presenting duo giggled behind the scenes.

But one participant stole the show and viewers took to social media to share their love for her.

And now the sweet foul-mouthed lady is set to delight viewers once more with another appearance. 

In a video released on social media as the show started, Dorothy, herself, revealed that she would be returning on tonight's programme. 

Speaking to the camera she told viewers: "Dorothy here, I'm on the show tonight.

"So make sure you're watching."
