The woman who inspired The Devil Wears Prada 's Emily Charlton felt "betrayed" by Emily Blunt's character.

Celebrity stylist Leslie Fremar has revealed she worked with author Lauren Weisberger during her eight months at Vogue magazine, which inspired her 2003 novel and the film adaptation three years later.

Speaking to Vogue boss Chloe Malle on the magazine's The Run-Through podcast, she admitted the book "felt like a betrayal".

Weisberger based Andy Sachs, played by Anne Hathaway, on her time as Dame Anna Wintour's junior assistant after being hired by Fremar, who was the inspiration for Emily Blunt's character Emily Charlton, while the character of Miranda Priestly (Meryl Streep) was based on Wintour.

Fremar said: "I know I am. I am Emily."

Quoting one of the movie's most iconic lines, she claimed: "I definitely told [Lauren] a million girls would kill for the job.

"That was definitely my line because I actually really believed that, and I knew that she didn't necessarily wanna be there."

When Wintour first heard that Lauren has written the book, she phoned Leslie.

The stylist recalled: "I was petrified. [Wintour] said, 'Who's Lauren Weisberger?' And I said, 'She was your junior assistant.'

"And she's like, 'Well, she wrote a book about us, and you're worse than me'.

"I wanted to, like, ask more questions, but you can't really ask her that many questions."

While she acknowledged the book and film were "fiction", she can't ignore a lot of the reality behind the story.

She explained: "It just felt like this exposure. Even though someone obviously advised her to make it fiction, it was really based off of a lot of things that, you know, I lived, she lived…

"I probably was not very nice, and I probably was high-strung because I felt like I was having to do her job as well.

"So for me, that was really frustrating. I think she was probably just sitting there writing a book and not necessarily taking the job as seriously as I did."

While she and Weisberger "never talked again after she left" Vogue, Fremar did get to meet Blunt after the first film.

However, she revealed: "I said to her, I was like, 'I just need to let you know, I'm Emily'. "She was not that interested, to be honest. I thought I was gonna get this, like, huge reaction. Like, no. It was like, 'Oh, OK.'"

Vogue icon Wintour has been viewed as the inspiration behind Meryl Streep's tyrannical magazine editor in the movie, and though she has previously avoided questions about the film, last year she admitted she thought the 2006 feature was "fantastic" and allayed the "sweet concerns" the fashion industry had about how she'd be depicted.

She told New Yorker Editor David Remnick on The New Yorker Radio Hour podcast, "I went to the premiere wearing Prada, completely having no idea what the film was going to be about.

"I think that the fashion industry were very sweetly concerned for me about the film, that it was going to paint me in some kind of difficult light... A caricature.

"First of all it was Meryl Streep, which, fantastic. And then I went to see the film, and I found it highly enjoyable. It was very funny...

"In the end. It had a lot of humour to it, it had a lot of wit, it had Meryl Streep. I mean, it was Emily Blunt. They were all amazing. And in the end, I thought it was a fair shot."

Hathaway, Blunt and Streep are reprising their roles in The Devil Wears Prada 2, which is released on May 1.
