She comes from a family of oversharers, but Kim Kardashian can keep a secret when she has to! The reality star, 33, opened up about the much-debated April cover of Vogue, which she shares with fiance Kanye West, on the Tuesday, March 25 Late Night with Seth Meyers.
"So, it was this top-secret mission trying to keep out all of my sisters and everyone," Kardashian told Seth Meyers, who was flabbergasted that her siblings Kourtney, Khloe et al didn't sleuth out that she, West and their daughter North West were posing for photos with Annie Leibovitz.

"They were a little suspicious," she conceded to Meyers, "but I just said Kanye was shooting something at my mom's house and it was really private, and just kind of blamed it on him."

One thing the E! star didn't know for sure herself was whether said photos and interview would land them on the cover. "I knew it was happening of course," Kardashian, 33, says, "but I didn't know it would be the cover. I'm just so honored."

Although baby Nori, 9 months, looks absolutely adorable in the final shots, she didn't completely behave herself during the sessions. "North peed on Kanye in that shot," she says of one image in which the trio hang out on a couch. "He was trying to tell me. I had to get up and clean him off."
Of course, since it's Kimye, the cover has elicited many, many haters -- including Sarah Michelle Gellar and Naomi Campbell -- but Kardashian's taking it all in stride, and embraces the milestones represented by the cover.
"Kanye's the first rapper, I'm the first reality star, we're the first interracial couple [on the cover]," she says.
