The much-loved Ant and Dec have taken a bit of a fall from grace for some viewers after a sketch they did last night about Stephen Hawking.

The hosts of 'I'm a Celebrity... Get Me Out of Here' were talking about a theory Gogglebox star Scarlett Moffatt had about time travel, telling her fellow campmates that she once even tried to email Stephen Hawking to see what he thought about it.

Back at the studio then, Ant and Dec then pretended to call the famous professor, using an electronic voice to impersonate the 74-year-old.

Watch the clip below;

In case you wanted the details of Scarlett's theory, she said;

"In order to travel back in time we have to go faster than the speed of light. The speed of light is like 319 and then loads of numbers, it’s exactly the same latitude point as the tip of the great Pyramid.

"So I think the pyramids are from the future, I think someone from the future realised we would need them and went back in time and built them."

Time is said to slow down near the you know, maybe Scarlett is on to something.... maybe.

Regardless of whether she is or not, people were not happy with Ant and Dec for the sketch...
