The actress, who has been the Chanel ambassador since 2008, married former Klaxons band member James, in France in May 2013 and they welcomed their first child, daughter Edie, in 2015.
In January, Keira spoke candidly about juggling a career while caring for her daughter and the emotional and physical journey that motherhood took women through.
She told Balance magazine: 'I don't think we give women enough credit for the physical and emotional marathon they go through when becoming a mother.
'I come from a place of amazing privilege. I have an incredible support system; I've been unbelievably lucky in my career; I can afford good childcare, and yet I still find it really f***ing difficult.'

The star of Colette added: 'It's OK to say that. It doesn't mean I don't love my kid, it's just me admitting that the sleep deprivation, the hormonal changes, the shift in relationship with my partner, are all things that make me feel as if I'm failing on a daily basis. I have to remind myself that I haven't failed, I'm just doing what I can do, but it's not easy.'
In October last year, Keira lamented the pressure on new mothers to look immaculate after giving birth in a candid account of motherhood.
The actress wrote about the 'vomit, the blood, the stitches' as she went into labour in May 2015, just a day before the Duchess of Cambridge welcomed Princess Charlotte into the world.

Kate famously left hospital just seven hours after being admitted to the Lindo Wing with both Charlotte and Louis in April, sparking a fierce debate on post-baby bodies.
In her essay, The Weaker Sex, Keira contrasted Kate's experience with her own, noting how the Duchess 'was out of hospital seven hours later with her face made up and high heels on'.
According to Refinery29 she wrote: 'My vagina split. You came out with your eyes open. Arms up in the air. Screaming. They put you on to me, covered in blood, vernix, your head misshapen from the birth canal. Pulsating, gasping, screaming.'
