looked unrecognisable as she went undercover for a hilarious advert on Friday.
The TV presenter, 55, wore a dark brunette wig with a side parting, clear glasses, and a blue Tesco uniform disguise in a bid to 'blend in' with staff members.
In a promotional video clip, the star can be seen helping shoppers, larking about in the aisles of the store, reducing groceries, working on the checkout tills, and chatting with people who are blissfully unaware of who she is.
At the end of the skit, Amanda exited the shop and tore off her disguise to reveal herself as a shocked passerby said: 'It's Amanda Holden'.
Speaking towards the camera, Amanda replied: 'Yes, it's me. Tesco helping you get everything you need. See you on my next shift,' before tossing her wig in the air.
Amanda has built a remarkable TV career over the years, but just last year, she said she would happily return to her Tesco cashier job if her showbiz career flopped.

Previously describing herself as a 'waitress that got lucky', Amanda said: 'If it all went t*** up tomorrow I’d be gutted, but I’d work as a cashier in Tesco again.'
She added: 'It’s about self-preservation, dignity and keeping going.
'I’ve waitressed, cleaned, made beds, picked fruit – anything I could to earn a living” she said, before adding ‘within reason.'
It comes after Amanda had viewers in hysterics as she made a racy confession about her bedroom prowess to her best pal , 49.
In a throwback clip from their BBC series, Amanda & Alan’s Italian Job, the TV star boasted that she was 'brilliant' in bed.
The Britain's Got Talent judge and the comedian took a break from fixing up their Italian property to try out one of the beds, with Alan taking the opportunity to quiz Amanda about her sleeping habits.
He asked: 'What are you like in bed? I mean do you move-' before Amanda quickly cut in to cheekily quip: 'I’m brilliant, apparently'.
As the Chatty Man star burst into fits of giggles, she smirked and added: 'Course I’m going to say that.'
Alan then clarified: 'No, I mean, do you move around?' and she replied by lying flat on her back with her hands folded on chest, adopting the position commonly called the 'mummy' or 'corpse' pose.
Amanda - who recently made another cheeky confession that she likes to wear a Sex And The City-inspired pearl thong at home - insisted: 'I sleep like this, and I don’t move.'
The hilarious interactions had fans in stitches, and they took to social media to praise the two besties, writing: 'Love you guys! You kill me! new series asap please!';
'I love you both you have me in hysterics of laughter'; Cheeky!'; 'Absolutely nutters. Love you both so much.'
