That's a sad state of affairs. Anytime a Kardashian makes it on the cover of a magazine (other than a trashy tabloid) is a world tragedy!!!!!
I think its pretty evident that she's not going to be on the cover of Vogue. She just shot a feature for Vogue Australia's content called Miss Vogue which is essentially a mini editorial on their website.
And technically...she's not a Kardashian, she's a Jenner.
Don't know where the rumor originates, but on Twitter, a lot of people are saying Kate Moss & Rihanna are on the upcoming UK Vogue cover, probably January then. I would think something different, with two of them like this, they would use for the March....
