The `Devil Wears Prada` actress - who is renowned for her sense of style - admitted she had more boyish interests and hated being dressed in feminine clothes when she was a youngster.
She said: "I never dreamed of being a princess when I was a child - I wanted to be on the soccer team. I wasn`t into Barbie dolls and swore I`d never, ever wear pink. I`d throw tantrums if my mum put me in pink clothes. Not a girlie girl at all."
However Emily - who married actor John Krasinski in Italy this summer - thinks being a tomboy has helped her to cope on male dominated movie sets.
She explained to Company magazine: "I like being one of the boys. It usually ends up being the case anyway because there`s often one female part to every five male parts on a film set.
"When you`re outnumbered you have to be willing to accept that there might be crass humour going around, but you get used to it."
