The excited mum, who was sitting down on her sofa at home alongside her family, unexpectedly appeared on the live show via a video link.
After being told by Ant McPartlin and Declan Donnelly that she had won a holiday, the guest hilariously whipped off her wig and shook it about in celebration.
The guest won the prize after her four daughters nominated her to producers for raising them as a single parent as well as overseeing a charity.
Both hosts struggled to get their words out following the moment, with Donnelly saying: “You raised four daughters on your own, and you run a charity providing toys, clothes and books to underprivileged children. Your kids say you’re a mum to everyone and we think you deserve a takeaway getaway."
When Donnelly threw it over to his co-host, the camera then revealed McPartlin to be un hysterics.
The moment cheered many viewers up, including Strictly Come Dancing star Oti Mabuse, who said: “So excited you pull your wig off!!! I HAVE BEEN THERE.”
Another added: “The wig on Ant and Dec’s Saturday Night Takeaway. I’m howling!! Thought Dec was gonna have a hernia he was laughing so hard.”
One person wrote: “If you didn’t see the woman whipping her wig off, on Saturday Night Takeaway after winning a holiday you’ve really missed out.”
Many people said the moment helped contribute to making last night’s outing “the greatest Saturday Night Takeaway episode ever”.
Ant and Dec’s Saturday Night Takeaway continues Saturday 20 March at 7pm
