One of the nation's favourite duos Ant and Dec returned to our screens last night - but viewers were left a little confused.

Britain's Got Talent had a 'virtual' audience, but it was presenters Ant McPartlin and Declan Donnelly who left people puzzled.

We've become used to seeing presenters stand at least a metre apart, following social distancing guidelines, but Ant and Dec were shoulder to shoulder on ITV last night.

But the MEN reports the pair are in a "bubble" together.

BGT aired last night

One viewer watching at home guessed on Twitter: "Ant and Dec being able to stand that near each other means they probably were in a bubble together.

"I’m choosing to believe it cause it’s a cute thought."

And their 'bubble' was confirmed on the show by the duo who explained: "We are indeed in a bubble, we have for a little while."

They added jokingly: "How long has it been? 30 years."

In England two households can be in a support bubble together, effectively becoming one household.

A regular bubble allows single adults living alone - or single parents whose children are under 18 - to form a support bubble with one other household of any size, but Ant and Dec have previously explained that their arrangement is a 'cohort' which means their households have close contact and they get tested every four or five days for coronavirus.

The issue was previously raised with Ant and Dec on BBC's The One Show, when they were asked to explain by host Alex Jones.

Pointing out they were in close proximity, she said: "I tell you what, people will be emailing, they'll be noticing you are very close together.

"Let viewers know what is happening, you are in a bubble aren't you."

Dec said: "We are in a cohort, is what it's called. We get tested every four or five days and our two households have now become a cohort."
