Anyone who's read The Devil Wears Prada will have a fair idea of the unwritten rules of the Conde Nast elevator: no bad outfits, no corn chowder soup and absolutely NO speaking to Anna Wintour.

But now the icy atmosphere of the Vogue publisher's lift has been thrown open to the public in all its lurid detail, thanks to a mystery tweeter under the handle name @CondeElevator.

Since the account was opened last weekend, @CondeElevator's postings - which claim to be snippets of conversations overhead in the elevator at Vogue's HQ in New York - have created a sensation.

Whether true or no, the tweets summarise in genius detail a cut-throat, sniping culture satirised so beautifully in Lauren Weisberger's hit 2003 novel (and subsequent film starring Meryl Streep, above).

Weisberger, a former assistant to Vogue editor-in-chief Anna Wintour, based her book on the claws-out world of fashion publishing, where fear and designers labels rule in equal quantity and boss "Miranda" is a force akin to deity.

@CondeElevator's tweets contain some very realistic echoes of the novel, with one co-worker telling another he was "not judging her" for eating a brownie and an intern complaining over her driver's "attitude."

The account has already amassed over 36,000 followers and executives over at Conde Nast - already hit by the PR shock of Devil Wears Prada - are understandably nervous (continued below).

@CondeElevator's best tweets:

The one with the driver:

Summer Intern: My driver had SUCH a bad attitude. I was like, "don't complain to me, I didn't eat lunch either! You think I eat clothes?"

The one with the like button:

Girl: Omigod I love your dress so much I wish there was a ‘like’ button I could press.

The one with the brownie:

The one with the cankles:

Fashion Girl Fl 12: Do these shoes make me look like I have cankles? Fashion Guy: No, they just have really fat straps.

The one with the war wound:

Girl: Omigod what happened to your knee?! Fashion boy: Oh god, I fell dancing! Girl: Omigod it's like you came back from the war.

The one with the omelette:

Woman #1 to Woman #2, holding an omelet: "What's the occasion?" Woman #2: "...huh?" Woman #1: "I would need an occasion to eat that."

A spokeswoman for the company told ABCNews.com that they had "no idea" whether the Tweets was real or made up.

"(We) don't know who is behind it but it certainly suggests that many people care a great deal about what happens at Conde Nast," she added.

Elsewhere, sources speculated that the tweets could come from a disgruntled intern.

One person based inside Conde Nast told the Daily Beast it could be "someone from one of the men’s books; a guy who has disdain for the hollowness of a lot of people in the building, a young guy who’s just like ‘Are you kidding me.’ Like a Details intern."

"The ironic thing is that people tend to stay fairly silent on the elevator, aside from one-on-one conversations, but many of those exchanges could definitely occur," another source told ABC. "I've never been accosted for my omelet, but I have gotten side-eyes for my burger at lunch on the way back up to my desk."
