Emily Blunt’s daughters thought she was one of the world’s “meanest” humans on Earth after they saw her acting in ‘The Devil Wears Prada’.

The 41-year-old actress, who has daughters Hazel, 10, and Violet, 7, with husband John Krasinski, 44, played catty fashion magazine assistant Emily Charlton in the 2006 comedy, and has now told how her character was so brutal it left her kids stunned.

She told Page Six about their reaction after seeing her performance: “They thought I was the meanest person they’ve ever me.”

Emily added about the lasting impact of the film on fans: “It’s incredible that it has such an indelible fingerprint on people… and it’s quoted to me every week.”

She added the cast, which included Meryl Streep, Anne Hathaway and Stanley Tucci, had the “time of our lives” working on the project, based on a Vogue-style magazine.

Emily said: “At the time I was young, it was my first big movie. I remember my agent calling me and telling me about the opening weekend.

“I was like, ‘Is that good?’ Like I didn’t know what was good.’”

The actress stressed she is nothing like her ‘Devils Wear Prada’ character by also opening up about her love of supporting charity the American Institute for Stuttering.

She said she was left “embarrassed” by the stammer she suffered as a child and had “begun to shut down” before she finally got help.

Emily added: “I never thought I would be in a job where I’d have to communicate so much… I do think it’s really ironic that I’ve ended up being in a job that is so public and full of so much public speaking.

“And I’m grateful because I love what I do.”

Emily added she wanted children who stutter to “speak openly” about the issued and don’t keep it “in the shadows”.
