The high street pizza chain say fans needn't worry they've missed out as the limited-edition pizza will be back on sale soon.
The creation, which is being made to celebrate National Pizza Day on the 9th February, feature Pizza Hut’s Classic Crust base and KFC’s iconic gravy, topped with mozzarella cheese, sweetcorn and, of course, the popcorn chicken.
It seems like it's been an instant hit with both KFC and pizza lovers, a spokesperson for the collaboration said: "We knew that the Pizza Hut Delivery KFC Popcorn Chicken Pizza would be a hit, but the demand has been wonderful. Everyone wanted a pizza the action and as a result, we’ve now temporarily sold out.
"In just one day, fans ordered just under 20,000 pizzas. Due to this phenomenal demand, the KFC Popcorn Chicken Pizza will be back soon… keep an eye out on the Pizza Hut Facebook page @PizzaHutUK and Twitter page @PizzaHutDeliver for updates on its return."
KFC re-iterated that even when it returns it will only be available for a limited time.
They confirmed that fans will only be able to order it – only in large – from the Pizza Hut website until the 16th February.
