These days, even household names seem perfectly comfortable slipping on a tinfoil hat in their downtime. Most recently, Kim Kardashian admitted she doesn't believe the moon landing actually happened - a claim she backed up with an alleged Buzz Aldrin quote. Predictably, the backlash came fast, with NASA itself chiming in (more on that later). Hulu/Disney+ And it made me wonder about all the other celebrities who've wandered into conspiracy territory. From B.o.B. getting into an actual rap beef with Neil deGrasse Tyson over flat-earth theories to Roseanne Barr amplifying QAnon talking points, plenty of famous faces have used their platforms to push some truly questionable ideas - many of which have been publicly debunked. So, here are 16 celebrities who openly shared their wildest conspiracy theories...and left the rest of us speechless. 1. Most recently, Kim Kardashian said that the 1969 moon landing "didn't happen" during a recent episode of The Kardashians, where she's speaking to Sarah Paulson. Kim explained that she read a quote from Buzz Aldrin about the scariest moment of his journey to the moon. "This girl says, 'What was the scariest moment?' And he says, 'There was no scary moment because it didn't happen. It could've been scary, but it wasn't because it didn't happen,'' Kim said. Elsewhere, she said that the Apollo 11 mission was "fake" and that there are "a few videos on Buzz Aldrin talking about how it didn't happen."

"And even better: @NASAArtemis is going back under the leadership of @POTUS. We won the last space race and we will win this one too." 2. Despite an overwhelming amount of information suggesting otherwise, Kyrie Irving jumped off the porch in 2017 when he claimed to be a flat-earther (spoiler alert: he won't be the only one on this list). He later apologized after the conversation sparked uproar, though he admitted that he enjoyed hearing people from both sides debate. Glenn James / Getty Images 3. For "Airplanes" rapper B.o.B., the flat-earth conversation resulted in a rap battle against...

Neil DeGrasse Tyson. B.o.B. went on a spree on X, formerly known as Twitter, explaining why he believes the Earth is flat and why he feels NASA hasn't been truthful about the world's edge. Tyson eventually responded back on X before B.o.B. took their beef to wax on a song called "Flatline," where he called Tyson out by name. In response, Tyson dropped a song called "Flat To Fact," written and recorded by his nephew Stephen Tyson. Julia Beverly / Getty Images 4. Ye (fka Kanye West) has made some egregious claims over the years, but one of the most insensitive and downright evil conspiracies he's pushed was that Derek Chauvin didn't actually kill George Floyd. During a controversial episode of the Drink Champs podcast, Ye spoke about Candace Owens's documentary on BLM and said that the former police officer's "knee wasn't even on his neck like that." He also said that "they hit [George Floyd] with the fentanyl." Matt Winkelmeyer / Getty Images The Hennepin county chief medical examiner told the court that Floyd died from "cardiopulmonary arrest complicating law enforcement's subdual, restraint and neck compression." As a result of Kanye's claims, Floyd's family filed a $250 million defamation lawsuit against him and sent him a cease-and-desist letter. 5. Terrence Howard publicly rejected basic arithmetic in favor of his own system of math that he calls "Terryology." In an interview with Rolling Stone, Howard explained how he believes 1x1=2. "If one times one equals one, that means that two is of no value because one times itself has no effect. One times one equals two because the square root of four is two, so what's the square root of two? Should be one, but we're told it's two, and that cannot be," he told the publication in 2015 about an argument he had with a professor when he studied chemical engineering at Pratt Institute in Brooklyn. He said he left school shortly after. "I mean, you can't conform when you know innately that something is wrong." Warner Bros. Tv / Getty Images 6. Jaden Smith has pushed some very odd theories throughout his life. In one instance, he told HuffPost that he believed there was a real-life Wakanda where the technology was light-years ahead of anything we're aware of. "I will keep it real broad and simple, real broad and simple. The technology that we're curr
