Scarlett Moffatt believes the Great Pyramid of Giza was built by time travellers.
The reality star's bizarre conspiracy theory comes after she recently claimed she was abducted by aliens as a child during an appearance on Loose Women.
But on Monday, Scarlett, 30, didn't hold back from sharing her beliefs on her BBC sounds podcast Scarlett Moffatt Wants To Believe.
Scarlett's boyfriend Scott Dobinson and This Country actress Daisy May Cooper joined in with the discussion.
She is convinced "time travel is real" and explained "the pyramids prove it," adding that the speed of light has "exactly the same" co-ordinates for the Great Pyramid of Giza.
"Basically Einstein and Stephen Hawking said if you could travel at the speed of light you could travel back in time," former I'm A Celebrity star Scarlett said.
"Because humans could not measure the speed of light back then to that precision, I reckon people from the future have travelled back in time to build the pyramid."
Daisy was left impressed by her theory, and responded: "The chances of 9 numbers written down in that order is a billion to one."
Scarlett further expanded on her theory, by stating hieroglyphics are "emojis from the future".
"There's a little helicopter hieroglyph, there's one that looks like UFOs, there's one that looks like a light bulb," she announced.
Hieroglyphs were the formal writing system used in Ancient Egypt.
It comes after Scarlett told the Loose Women she was abducted by aliens when she was just 10.
Chatting to Andrea McLean, Gloria Hunniford, Brenda Edwards and Nadia Sawahla on ITV's daytime show, Scarlett explained that one of her earliest memories was looking for crop circles in fields with her father with a notepad, and she was convinced she had found them.
She said she saw a huge beam of light come into her bedroom, and then she had a dream about being abducted by aliens.
But she thinks it was more than just a dream, and revealed her boyfriend Scott thinks it's "a load of rubbish".
"I think they wanted us to think it was a dream, Scott seems to think that it was just a car headlight, and it probably was just a dream," Scarlett confessed.
