Kardashian, 33, stunned in a cleavage-baring white dress with a high slit. She kept her chestnut locks down in waves and wore minimal makeup.

Just hours earlier, the Keeping Up With the Kardashians reality star was freaking out (Along with everyone else via social media!) about her cover with fiance Kanye West that was shot by celebrity photographer Annie Leibovitz.

'This is such a dream come true!!!Thank you @VogueMagazine for this cover! O M GGGGGG!!! I can't even,' she gushed on Twitter. Later, she posted, 'Please welcome @annieleibovitz to twitter! She is the legendary photographer who shot our @voguemagazine cover! Love u Annie! #BestMemories,' she later added.

Kardashian, West, 36, and their daughter North West, 9 months, were all featured in a behind-the-scenes video on Vogue.com as well.

In the magazine, Vogue's editor-in-chief Anna Wintour wrote an explanation of her decision to put the couple on the cover, explaining that West, who has been outspoken about getting his fiancee on the cover, was not a factor.

'Part of the pleasure of editing Vogue, one that lies in a long tradition of this magazine, is being able to feature those who define the culture at any given moment, who stir things up, whose presence in the world shapes the way it looks and influences the way we see it,' Wintour, 64, wrote.

'As for the cover, my opinion is that it is both charming and touching, and it was, I should add, entirely our idea to do it,' she continued. 'You may have read that Kanye begged me to put his fiancee on Vogue's cover. He did nothing of the sort.'
