Sienna is looking ethereal on the cover of the new January 2013 issue of Harper’s Bazaar UK! The 60′s looking photoshoot inside is accompanied by a new interview in which Sienna talks about motherhood, amongst other things.

Within this post are some released quotes from the interview, a behind the scenes video from the photoshoot, and Harper’s Bazaar’s article announcing the issue. And in the Gallery you can find the cover and first two photoshoot pictures. We’ll have scans asap!

“It’s still the most surreal thing, that you can create, that I grew this life inside my stomach, her eyeballs, everything – every little fibre. And I’d expected that she’d be this extension of me and I’d instantly understand who she was because she’d come from me, and then you realise that they are their own people entirely. Very connected to you, of course. But they’re their own person.”

“It’s just been the three of us, which was amazing, and exhausting. We are going to get a nanny, but it felt important to first learn for myself who I was as a parent.”

“It’s the best, the greatest thing in the world… I would do that day a million times again. I would do that day, every day. I loved it. [My body is] not mine – all the attachment to its flaws or any aesthetic attachment is gone. You understand what breasts are for; and I have such enormous respect for my body because of what it can do.”

The magazine hits news-stands on Monday.

Bazaar meets Sienna Miller

Our brilliant January issue, themed around the body, welcomes a new editor-in-chief and a compelling cover star.

For the January issue of Harper’s Bazaar, editor-in-chief Justine Picardie takes the helm for the first time, marking a fresh chapter in the magazine’s illustrious history.

Themed around the body, the issue encompasses an art detective story about Titian’s voluptuous subjects, a grown-up’s guide to achieving modern health and beauty and a candid first-person account by writer Tanya Gold on her own journey to self-acceptance.

Our cover girl is Sienna Miller, an actress who has weathered public storms to emerge triumphant as an increasingly respected talent and blissfully happy mother.

She talks frankly to Justine Picardie about her wild child past and the new serenity she’s found with partner Tom Sturridge and their baby daughter Marlowe.

Photographed by David Slijper and styled by Leith Clark across 11 pages of Bazaar, Sienna wears designs from Stella McCartney, Louis Vuitton and Chloé, channelling a Sixties vibe that is feminine yet contemporary.

It’s a shoot in perfect keeping with Bazaar’s new mood for 2013, which combines an ultra-modern sensibility with a celebration of our proud heritage.

To mark that history, and in the irreverent spirit of the great Diana Vreeland, Harper’s Bazaar brings back her famous fashion editor’s column Why Don’t You.

Often inspired, sometimes eccentric but always life-enhancing, we hope it adds a little joie de vivre to your day.
