Khloe Kardashian helped persuade Kim Kardashian that the 1969 moon landing "didn't happen".

The Skims founder recently caused a stir when she attempted to convince her All's Fair co-star, Sarah Paulson, 50, to side with her and other conspiracy theorists that Buzz Aldrin, 95, and the late Neil Armstrong's Apollo 11 mission did not happen, and now her sister has admitted she and their brother Rob Kardashian were responsible for getting their older sibling "riled up" about the conspiracy.

Khloe admitted to People magazine: "I don't believe in the moon landing. That's very controversial. And I feel bad because I think I riled Kim up about it, and I've gotten her into a lot of trouble!

"I don't think it happened. I think me and my brother, we've fed her a lot of information. I don't know, I feel bad about that, but I'm going to die on this hill!"

The Khloe in Wonderland podcaster admitted she is interested in other conspiracy theories but tries to keep her views to herself.

She said: "I don't expect the government to admit the moon landing was faked, because then if they admit that didn't happen... I mean, there's a long list of things you can look into, and some are too scary to talk about publicly because you don't want anyone getting mad at you."

Kim told Sarah in between takes of their Hulu drama, captured in the October 30 episode of The Kardashians, that she believes the 1969 moon landing was fake because Aldrin says " it didn't happen" in interviews.

Kim also alleged that Buzz's old age makes him blurt out comments like that, before ultimately ruling: "So I think it didn't happen."

Later in the episode, a producer approached Kim's trailer and asked the star to confirm her belief that the astronauts did not walk on the moon.

Explaining how she was convinced of the conspiracy theory, Kim added: "Why does Buzz Aldrin say it didn't happen?

"There's no gravity on the moon - why is the flag blowing? The shoes that they have in the museum that they wore on the moon [have] a different [foot]print than the photos.

"Why are there no stars?"

NASA's acting administrator, Sean Duffy, then spoke out to try and persuade her otherwise.

The 54-year-old official - who is also the United States Secretary of Transportation - wrote on X: "Yes, @KimKardashian, we've been to the Moon before… 6 times!

"And even better: @NASAArtemis is going back under the leadership of @POTUS [President of the United States, Donald Trump].

"We won the last space race, and we will win this one too 🇺🇸. (sic)"

Apollo 11 was the first moon landing, which took place in July 1969, with Armstrong and Aldrin.

This was followed by Apollo 12 in November 1969, Apollo 14 in February 1971, Apollo 15 in July 1971, Apollo 16 in April 1972, and Apollo 17 - the latest crewed mission to the Moon, which took place in December 1972.

According to NASA's website, the Artemis campaign involves the exploration of the Moon for "scientific discovery, technology advancement, and to learn how to live and work on another world as we prepare for human missions to Mars".

After Secretary Duffy responded to Kim's belief that the 1969 moon landing did not happen, the star replied in his post's comments section.

She penned: "Wait…. what's the tea on 3I Atlas?!?!!!!!!!????? (sic)"

3I/ATLAS is one of only three interstellar comets seen by astronomers, and it was discovered on July 1, 2025. Unlike other comets, it does not orbit the Sun.
