The Hollywood veteran, who inadvertently announced La La Land as Best Picture at this year's ceremony -- instead of actual winner Moonlight -- after she and Warren Beatty were mistakenly given the wrong envelope by a PricewaterhouseCoopers rep backstage, broke her silence on the infamous gaffe during a recent interview with NBC News' Lester Holt.
"I was very guilty," she shared, expressing regret that she didn't realize sooner that the envelope was for Best Actress. "I thought, I could have done something, surely. Why didn't I see Emma Stone's name on the top of the card?"
"Something about that moment ... just combined to make us both not able to perform what normally one would perform," she continued. "Normally, we would say, 'This is the wrong card.' But it didn't happen that way."
When asked whether she and Beatty would be able to laugh off the incident one day, Dunaway responded, hilariously, "Not really."
