The reality star is currently expecting her second child with husband Kanye West and, while many would think the forever-glam 35 year old is still keen on maintaining her high levels of fashion, Kim admits she has let herself go a bit, choosing comfort over style.

"It's getting hard," she tells Vogue fashion guru Andre Leon Talle. "A friend of mine emailed me and said, 'Have you given up?' and I said, 'Why, what do you mean?' and he said, 'You're wearing flip flops. I saw a photo of you in flip flops', and I said, 'Yes, I've given up at this point'."

Kim plans to welcome her son via C-section on the morning of Christmas Day (25Dec15) and now she's preparing for the big delivery. The star usually boosts her petite frame with skyscraper heels, but the mother-of-one is struggling to get her swollen feet into her favourite pairs.

"I'm to the point now where my feet are slightly starting to swell - not as bad as before - but they're getting there," she continues. "Today I'm wearing heels and they're fine. I think in spurts they're OK at this stage. I'm so close to completely relaxing and doing absolutely nothing, and I can't wait for that time."

Kim has also been doing her best to stick to a healthy diet, enjoying egg whites and avocado for breakfast and a salad for lunch, but she tells Andre that her sweet tooth does kick in from time to time and she even flew to Paris for the day just to have a slice of her favourite cheesecake.

"It's heaven," she said. "I flew in, maybe, like, a couple months ago, just to have a last hurrah of all the food I'm not going to be able to have for a while, and I get there and they tell me they didn't have it! (I said) 'You don't understand, I leave tomorrow and I flew all the way over here for one night, maybe two nights', and they said 'OK, we're going to get it'. And they got it and it really made my day."
