The 33-year-old actress - who was born and raised in London - is devastated two-year-old Hazel has already started to pick up her Massachusetts-born father John Krasinski's native tongue.

Speaking to 'The Hollywood Reporter', she said: "She's [Hazel's] sounding a bit American from what I see. [She says] 'Can I have some wah-ta?' I was like, "Wodder?" And she went, 'No, it's wah-ta.' I was like, 'Oh, for God's sake!' "

But the 'Girl on the Train' star hasn't always had perfect pronunciation herself, as from a young age she has struggled with a stutter, although she believes her school teacher - who taught her from seven until she was 14 - helped her conquer her stammer by throwing her into acting.

However, the blonde beauty saw her speech difficulty return when she was pregnant with her second child Violet, now three months.

She explained recently: "I've sort of grown out of it, but funnily enough when I was pregnant [with Violet] it came back quite prominently. That was interesting."

Emily may have a busy screen career and two young children to look after but she insists she is a lot more chilled out this time around when it comes to motherhood.

She said: "I wonder if it's the second kid - you're so relaxed, and then they're relaxed. Your energy is not like, 'Oh my God, am I gonna kill this child by something that I'm doing?' "

And she can't believe how well Hazel has adapted to her sister.

She explained: "She's [Hazel] taken to it well. She's doing brilliantly, she's very kind to her [Violet] ... She was sort of indifferent, and then really loved her."
