I'm A Celebrity... Get Me Out Of Here! star Scarlett Moffatt revealed that she tried to get in touch with renowned physicist Stephen Hawking after coming up with her own time travel theory.
Speaking to her fellow jungle camp mates on Wednesday's show, she explained: "I once emailed him because I had a theory about time travel.
"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."
Fellow camp mate Adam Thomas agreed he was "with that" theory, but Scarlett revealed she struggled getting her revelation across to Professor Hawking because she doubted the Hotmail address she found for him was likely to be real.
She proved she was not his only fan, as Sam Quek recalled how she was star struck when she met Prof Hawking at an awards ceremony.
The British hockey player, 28, said it was the "first time I ever felt in the presence of a legend".
I'm A Celebrity... Get Me Out Of Here! continues on Thursday at 9pm on ITV, when the jungle camp mates will be joined by new additions to the show, Danny Baker and Martin Roberts.
