Keeping up with Kim Kardashian! The reality superstar opened up to London's Evening Standard magazine about everything from her secret to getting North West asleep to her fairy tale wedding — which was orchestrated by Kanye West.

The working mom admitted that when it comes to getting little Nori to bed, "there are some nights that are longer than others" and that "it is tough," but she and West have two techniques they've mastered — and one (ironically) is loud music.

"[I give her] a bottle at night with some cereal in it," Kardashian said of her 16-month-old mini-me. "I put in the milk, and then the rice cereal, and then you have to cut the nipple a little bit more to let it pass through, and it fills North’s tummy and she’ll pass out."

Nori's rapper dad West, 37, helps lull their baby girl to sleep as well. "The best is when Kanye’s recording in the home and we’re in Mexico or wherever, and the music will be upstairs and she’ll hear it, and it’s really loud and you’d think it would disturb her, but I just kind of rock her to it, and she’ll just pass out [too]," the E! star added.

Speaking of West, the 34-year-old credits her hubby for pulling off their May fairy tale wedding and for coming up with a majority of her business ventures.

"Kanye comes up with every idea that is so, I think far out of reach, but then he makes it happen," Mrs. West gushed. "He was like, 'We are going to go to Versailles, and we should have our wedding at the Louvre,' and I was like, 'What?' There’s obviously music restraints and constrictions at a lot of places like the Louvre. And then maybe four weeks before the wedding, I thought we were set and done and he said, 'Let’s move it to Florence,' and I was like, 'What?' And he was like, 'And let’s not tell anyone so that we can surprise everyone the night before and have everyone go to Paris and then we’ll fly everyone to Florence.' And I [said], 'Are you crazy? This is never gonna happen -- we can’t move the wedding, how is that possible?' And he was like, 'Babe, everything is possible.'"

"That's my favorite quality of his," the fashion designer added. "He literally thinks everything is possible. But, the craziest thing is, that it all happens."

Aside from making their lavish May 24 nuptials a dream come true, Kardashian said her hubby is also the one responsible for coming up with her selfie book idea.

"Kanye came up with the concept and the name and everything," she told the mag of her book appropriately titled Kim Kardashian Selfish. "He introduced me to the book publisher. And I was like, 'This is such a good idea, I can’t believe I didn’t think of it.' But you know, I’ve been taking selfies for a long time — it’s like now [seen as] such a vain thing, but it really started off with me just having a camera around to capture memories. They’re selfies taken over a decade. It’s 352 pages and multiples on the page, so I turned in probably 2,000 selfies."
