There's a self assuredness in Sienna Miller's new Vogue cover story.
The 41-year-old actor speaks about overcoming the need to prove herself with only serious, 'important' roles. Her friends tell stories of her pushing back against paparazzi shouting rude things. She pushes back at the suggestion that her younger partner, 27-year-old partner Oli Green, may want to be with someone younger one day, by simply stating, "For Oli, it is real that I might want to be with someone older".
But there is one part where Miller admits she's still has an insecurity to work through.
Watch: the horoscopes as new mums. Post continues below video.
Miller is 28 weeks pregnant with her second child, and her first with Green. She is already a mother to 11-year-old Marlowe, who she co-parents with actor Tom Sturridge.
"I'd love to get to a point where I didn't feel the need to make a joke of my being older and having a baby, to show I'm in on the joke," she said.
Besides that, Miller says she's up for surrendering to the process this time around, in a way that she wasn't when pregnant with Marlowe.
