The 'Mary Poppins' star - who has Hazel, four, and Violet, 22 months, with her husband John Krasinski - says her children's happiness is the "most paramount thing" in her life.

She said: "My children's happiness, their safety and their well-being is the most paramount thing in my life. And if [I am] unable to give them any of those things, then who am I? What's my identity? My greatest hope is that they are truly happy, and that they're interested in life, in anything. Interested and interesting, and truly happy."

And John wants to "protect" his children at all costs.

He added: "Even when [we] drop our four-year-old daughter off at school, you don't know what she's gonna do that day. You don't know if other kids are gonna be nice to her or if she [will get] in trouble for something. You just want to protect them at all costs."

And the 35-year-old actress starred alongside her husband in 'A Quiet Place' and says he "surpassed her expectations".

She told People Now: "He just surpassed my expectations in every way. It was really exciting. And I think the other thing that surprised us was probably how well we worked together, 'cause we were a little bit trepidatious about it, and we loved working together."

Meanwhile, Emily previously confessed she is a "different person" now she has children.

She said: [Being a mum] changes your world completely. You become a different person, because you look at your choices from a different perspective. Whenever I'm considering a project, I always think how it's going to affect the lives of my daughters. You learn that you're actually more capable than ever."
