A managing partner at PricewaterhouseCoopers LLP posted a celebrity photo on Twitter backstage at the Academy Awards on Sunday night just minutes before he mistakenly gave an envelope to actor Warren Beatty that set off the disastrous announcement of the wrong best-picture winner.

Brian Cullinan, one of two PwC partners holding envelopes with the names of Oscar winners, tweeted “Best Actress Emma Stone backstage! #PWC” along with a photo of the actress at 9:05 p.m. Pacific time. That was approximately three minutes before Warren Beatty and Faye Dunaway walked on stage to present the award for best picture.
