This is pretty shocking ... a rep for the Academy tells TMZ, Michelle Obama was in fact the ONLY person in the White House to view the contents of the Best Picture Oscar envelope last night.
TMZ broke the story ... it's practically inconceivable that any package -- even a high-profile Oscar envelope -- would reach the First Lady without being thoroughly vetted first.
But a rep for the Academy tells us, "First Lady Michelle Obama was the first and only person to open the Best Picture envelope. PwC [PricewaterhouseCoopers] accountants are the only individuals who have knowledge of the results prior to their live reveal on the Oscars."
As we reported, TMZ spoke to the Secret Service this morning ... and they said, "We're not gonna comment on that."
We're not sure if we're relieved or terrified.
