Kate Hudson for Harper's Bazaar US December/January

Kate Hudson is the latest cover star of Harper’s Bazaar US, shot by Alexi Lubomirski for the December-January issue who captures the blonde star wearing Lanvin for the newsstand cover and Givenchy for the subscriber cover, plus a dazzling array of Spring 2014 looks from the likes of Tom Ford, Alexander McQueen, Roberto Cavalli and Fendi are featured in the editorial.

She talks to the mag about fitness, family, high-end shopping and my favourite top red-carpet fashion.

On high-end clothing: “People think we own all these dresses. But we borrow them. I can’t afford to buy that stuff. There are certain things I splurge on, but it’s very rare, especially when you have two kids and school tuition. I’m not a big high-end fashion shopper. I wish I could but the truth is things are just so expensive. Before Isabel Marant was a million dollars and famous, I used to go to her store in Paris and go crazy, it was so affordable.”

On the beaded denim Balmain minidress she wore to the ‘Clear History’ premiere: “It was a bit intimidating. The workmanship is amazing. It brought me back to being a little girl looking at anything sparkly.”

On her favourite red-carpet moments this year: “The black-and-gold Alexander McQueen dress I wore to the Golden Globes, and a red Stella McCartney and a red Prabal Gurung. I haven’t really done Valentino yet, but I want to.”

On staying active: “It really is a vital part of my day in terms of energy. And I mean just by putting a sports bra on. Then maybe you’ll do something. Even if it’s a few squats in the backyard and back to the couch.”
