He has been a cricketer, boxer and most recently host of Australian Ninja warrior, but now Andrew ‘Freddie’ Flintoff has joined the Flat Earthers.
The English former cricket all-rounder, despite the overwhelming body of evidence against it, has declared he believes the world is not round, but flat.
The Daily Mail reported Flintoff declared himself a flat earth enthusiast after listening to a podcast called The Flat Earthers.
He says "evidence suggests the world isn't round", asking: "If you're in a helicopter and you hover, why does the Earth not [rotate under you] if it's round?"
He also asked: "Why would water stay still if we're hurtling through space? Why is it not wobbling?"
Flintoff played a number of Ashes series in Australia and would have flown there in a plane whose navigation system depended on the world being round.
Science also suggests that if the world was flat, gravity would be very different nearer the edge than the middle, making cricket almost impossible to play in some countries.
None of that seems to bother Flintoff, who has also declared the moon landings were fake.
The Flat Earth movement has had some minor celebrity endorsements recently.
In September US rapper Bobby Ray Simmons set up a crowdfunding appeal to raise money to take satellite images of the earth to prove it is flat.
Ex-basketball player Shaquille O'Neal has also declared himself a believer.
Robbie Davidson, organiser of the Flat earth National Conference told the Daily Mail: “You're going to see more celebrities and scientists come aboard. This is just the beginning."
