Harper’s Bazaar’s new editor Justine Picardie has chosen Sienna Miller as the cover girl for her launch issue next month.

Themed around ‘the body’, the January edition features an in-depth interview with the actress.

Sienna has had a busy year, between her court battle with the press and having a baby girl, she is described by the mag as being in ‘the next stage’ of her life and reveals details of birth and life as a parent:

On being a mother: ‘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.’

On Childbirth: ‘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,’

On her body: ‘My body’s a completely different thing to me, it’s 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.’

On hiring a nanny: ‘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.’

Photographed by David Slijper and styled by Leith Clark across 11 pages, Sienna wears Stella McCartney, Louis Vuitton and Chloe for the shoot, channelling a Sixties vibe ‘that is feminine yet contemporary.’

We think she looks beautiful.
