In case you needed a reminder, yes we are in the year 2017, and yes there are people that think Earth is flat.
And not just your regular "Mad Mike" characters. Oh no, a number of celebrities in the past few years have come out in favor of the bizarre theory.
From basketball players to musicians, a number of celebrities are jumping on the flat Earth bandwagon. You'd hope that most of these aren't actually being serious but, hey, a climate change denier is currently President of the United States. Anything goes it seems.
So here are a few celebrities who, for one reason or another, have expressed the view that they think the Earth is flat. I'm looking forward to seeing what exciting conspiracy theory makes its way into the public mainstream in 2018.

Kyrie Irving is the celebrity that arguably started this recent bout of flat Earthness. In early 2017, the Cleveland Cavaliers' guard said he thought Earth was flat.
"This is not even a conspiracy theory," he said in February. "The Earth is flat. The Earth is flat. It's right in front of our faces. I'm telling you, it's right in front of our faces. They lie to us."
Irving doubled down on his beliefs multiple times. But in September, he claimed that the whole thing had just been a "social experiment", and he had spun the world "into a frenzy".
So, it was all just a joke? I guess. Haha. Very funny.

Irving may have been joking, but that didn't stop a number of other basketball players coming out in support of the flat Earth theory.
Los Angeles Rams receiver Sammy Watkins supposedly also believes Earth is flat, although maybe he was in on the "joke" too.
There's also Golden State Warriors forward Draymond Green, who said he didn't know if the Earth was flat, "but it could be".
And there's Denver Nuggets forward Wilson Chandler, who in February tweeted: "I agree with him" in response to a now-deleted tweet about Irving.
Shaquille O'Neal, too, also got involved, later claiming he had been joking that he thought the Earth was flat.
Who's being truthful? Is anything real? Is Earth really flat?! I just don't know.
B.o.B
While we're not sure if those basketball players were just pulling our leg or not, rapper B.o.B seems pretty adamant the Earth is flat. At the start of 2016, he tweeted a string of bizarre comments supporting the idea.
"A lot of people are turned off by the phrase ‘flat earth’ ... but there’s no way u can see all the evidence and not know... grow up," he said.
"No matter how high in elevation you are... the horizon is always eye level ... sorry cadets... I didn’t wanna believe it either.”
This led to a now rather infamous "rap battle" with astrophysicist Neil deGrasse Tyson, who took it upon himself to debunk most of B.o.B's musings.
Yes, B.o.B could have been joking too. But a cursory glance at his Twitter feed suggests that's probably not the case.
Just a few days ago, for example, he sent this bizarre tweet: "now realize that there is no earth... there is only now." Yep.
He shot to the fore again in September, when he was apparently seeking money for a crowdfunding campaign to send a satellite into orbit and test if Earth was flat.
That looks like it might have been fake, however, so perhaps B.o.B will never get the answers he's seeking.
Tila Tequila

I'm not 100 percent clear on who Tila Tequila is, let alone how she became famous. I hear it has something to do with Myspace, but hey, apparently she's a celebrity.
And last year, she made headlines (again?) when she repeatedly tweeted that she thought Earth was flat, and wanted someone to tweet her evidence it wasn't.
"I WILL STOP MY #FLATEARTH TALK IF SOMEONE CAN SEND ME A GOD DAMN PHOTO OF THE HORIZON WITH A CURVATURE!" she eloquently wrote. Lovely.
She also queried why buildings in New York would stand straight up, rather than tilt, if Earth was round. Please don't make me explain why this isn't the case.
Aside from thinking Earth is flat, the Trump supporter also appears to have some questionable views in favor of Hitler, and has been pictured making a Nazi salute at a far-right rally. How nice.
Freddie Flintoff

Those of you in the US might not know who Freddie Flintoff is, but here in the UK he's a pretty famous cricketer who was instrumental in England's defeat of Australia in the 2005 Ashes series.
He might be good at cricket, but it appears he's not that good at science. Speaking on a podcast for BBC 5 Live in the UK last week, he expressed some rather bizarre views and said there was evidence suggesting the world wasn't round.
"If you're in a helicopter and you hover, why does the Earth not come to you if it's round?" he asked his co-hosts. The answer, dear Freddie, is relativity.
He also didn't understand why water stayed still if we were hurtling through space (gravity), and why you can see a laser that you fire into the distance. Not sure what he's going on about here.
"The middle is the North Pole, around the outside is the South Pole which is like a big wall of ice," he said. "This is why all governments now have bases on the South Pole."
I, uh... okay. I see.

Okay, so WWE wrestler Styles didn't explicity say he thought Earth was flat, but he did make some comments that alluded to the fact he might believe just that.
"I don't think the world is flat, I'm just saying there's some stuff about it," he said earlier this year. "That's all. I'm not a flat earther. I'm just saying there's some things about it that make sense."
Uh huh.
Then there was Sherri Shepherd, who was given quite a hard time for comments she made on The View back in 2007.
When asked if the world was flat by Whoopi Goldberg, she responded: "I don't know. I never thought about it Whoopi. Is the world flat? I never thought about it. I tell you what I thought about, how I'm going to feed my child."
Shepherd got a huge amount of stick for the comments, and later clarified that she didn't think the Earth was flat.
But it goes to show that, when it comes to Earth being flat, you're probably best to stick on the side of science.
