Britain’s Got Talent’s Ant and Dec’s make shock discovery backstage on the show – and fans are all saying the same thing

BRITAIN'S Got Talent hosts Ant McPartlin and Declan Donnelly have taken to solving mysteries between takes.

The pair, both 46, stumbled across a giant safe at the London Palladium - and it didn't belong to Simon Cowell.

The pair seemed determined to know why it was there - and more importantly what was inside.

Dec filmed them snooping around, asking his co-host: "What do you think's in there?"

Ant replied, matter-of-factly: "A safe? Money."

Dec asked: "Money? Money you say. How much money? I'd love to know what's in it."

When they inspected the safe they found it branded with the words "fire and thief resistant".

Ant explained: "I reckon they used to take the money from the box office, put it in some kind of system, where it would go down the tubes and then end up here."

"You'd take the cash boxes out and take it to the bank in a bowler hat and a pinstripe suit. And it would be the bank from Mary Poppins.

"And Mr Banks would work there, but he would work too hard and he wouldn't spend time with the children.

"So Mary Poppins had to come down with the umbrella to play with the children to remind the dad that there's more to life than work.

"Want to know any more about this venue?"

Dec, having rapidly lost interest during Ant's theory, replied: "No I've heard quite enough."

However, many fans thought the safe was where the multi-millionaires' fees for hosting Britain's Got Talent were being kept.

One comented: "Your wages are in there 😮😂."

Britain's Got Talent returns to ITV at 9pm on Saturday
