It's a lesson many have Secret Confessions: Wifey’s BFF Episode 48to learn the hard way: Don't tweet.

The Wall Street Journalon Monday reported that Pricewaterhousecoopers U.S. board chair Brian Cullinan was the one who handed the wrong envelope to Warren Beatty. Turns out he did so right after tweeting a photo of Emma Stone.

That tweet -- and several other photos Cullinan tweeted that night -- has been deleted.

It seems that the chair of Pricewaterhousecoopers -- which has had this Academy Awards gig for more than 80 years now -- handed presenter Warren Beatty the wrong envelope, after snapping a pic of Stone.

On one side of the stage was Brian Cullinan himself, and on the other, was his colleague Martha L. Ruiz, now participating in her third Academy Awards.

As we now know, sealed inside Beatty's envelope was the duplicate card featuring Emma Stone's name, who had accepted the Best Actress award just moments before. Beatty got visibly flustered and deferred to co-presenter Faye Dunaway, who saw the words "La La Land" on the card and blurted it out.

The confusion that ensued included Beatty's on-stage explanation, Stone's backstage questioning of that explanation and, finally, a late-night statement from Pricewaterhousecoopers ultimately claiming responsibility.

ABC/Disney, which distributed the PwC mea culpa statement, did not immediately respond to requests for clarity. Neither did a PwC rep immediately return calls and emails.

Now we have a since-deleted tweet thickening the plot of an already very wild Oscars story.

The truth is out there.
