BBC viewers were left disgruntled mere minutes into the show when Michael McIntyre introduced an unexpected guest.

Lorna Brown, 41, from West Lothian was introduced, who had journeyed to London for a weekend break with her husband Scott, their three children and her parents. Michael informed viewers: “She thinks she’s about to check into an AirBnb which we have built here,” as he gestured towards a door on stage.

He offered a brief tour of the backstage apartments and hinted at a surprise waiting for her inside a makeshift fridge, which concealed the show’s live audience. After a series of playful antics, including Lorna watching Strictly Come Dancing’s head judge Shirley Ballas perform a risqué routine with an audience member, she finally opened the fridge door.

To Lorna’s astonishment, she emerged onto the stage to a thunderous applause from the theatre audience. However, viewers weren’t convinced that the surprise star was unaware of her impending appearance on Michael McIntyre’s Big Show.

“No, but then I started to think something is going on,” the participant admitted. Overwhelmed with emotion, Lorna disclosed her passion for music, revealing she leads a community choir and has been singing since she was eight years old.
