High Lane Oatcakes in Stoke-on-Trent said the shop has been "ridiculously busy" after Robbie Williams told a press conference he wouldn't have oatcakes from anywhere else.
The musician grew up in Tunstall, about half a mile away from the shop.
People were queuing out the door when Radio Stoke went to see the shop, which now has a reputation for providing "oatcakes to the stars".
"His mum always comes in to get them for him," Milly, who works there, said. But only the fruit ones, mind - "he doesn't like the plain ones".
