Sienna Miller has spoken out for the first time to reveal how motherhood has changed her.
The Layer Cake actress, who welcomed baby Marlowe with boyfriend Tom Sturridge four months ago, has spoken openly about adjusting to being a parent - describing childbirth as the "greatest thing in the world."
Speaking to Harper's Bazaar, Sienna revealed: "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 still the most surreal thing, that you can create, that I grew this life inside my stomach, her eyeballs, everything – every little fibre."
The actress gushed that she's finding her new role as a mother "the best."
"I’d expected that she’d be the 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," she explained.

"Very connected to you, of course. But they’re their own person. 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 love it."
Sienna admitted that since childbirth, she sees her body in a completely new way and has a new-found respect for it.
"My body’s a completely different thing to me," she told the magazine.
"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."
