Emily Blunt's stutter came back when she was pregnant.

The 32-year-old actress - who has 20-month-old daughter Hazel with husband John Krasinski - began acting as a child as a way of overcoming her speech difficulties and though she eventually ''grew out of'' the impediment, she was surprised when it suddenly returned.

She said: ''I've sort of grown out of it, but funnily enough when I was pregnant it came back quite prominently. That was interesting.''

The 'Sicario' actress admits motherhood has changed her profoundly and she loves the feeling of having a constant ''lovely distraction'' in her life.

She told Radio Times: ''It changes you infinitely in a rather overwhelming way.

''The best way I can describe it is that it's like this lovely distraction that I always have. It's always there and I love that feeling.''

The British actress currently lives in Los Angeles with her family, but has mixed feelings about the city.

She said: ''It's complicated. I love so much about LA and I hate a lot about it too.

''I hate that it's a one-industry town and that the quest for success emanates from every corner of it. It can be suffocating in some ways.

''But I love my friends there, I love the weather and it's a very easy place to raise a child.

''A lot of time we lie outside of LA in the countryside, in a place called Ojai, which is lovely and offers more respite than the city.''
