Moment of truth.

Kim Kardashian finally revealed why she and mom Kris Jenner suspiciously deleted their photos of Meghan Markle and Prince Harry off Instagram last November.

“It was really innocent, which is so crazy,” the Skims co-founder said on her sister Khloé Kardashian’s “Khloé In Wonder Land” podcast Wednesday.

“Mom and Meghan have been friends for some years now, and they have a really sweet relationship,” Kim, 45, added.

The mom of four said she and the famed momager went through photos from Jenner’s star-studded 70th birthday bash to see which snaps they would post online.

“We were told that it was totally cool to post. And then after it was posted, I think they realized it was Remembrance Day, and they didn’t want to be seen at a party, even though it’s already up, you know, and then taken down,” Kim recalled.

“And then I think they realized, like, ‘Oh, this was so silly,'” she added.
