Another first for President Obama's White House.
The first first lady to award the Oscar for Best Picture.
Michelle Obama did the honors late Sunday night, telling the world that Argo had been voted the year's top film.
Mrs. Obama -- appearing at the Oscar ceremony via satellite from the White House, where she and the president had just hosted a dinner for the nation's governors --also paid tribute to all the nominated films.
"These nine movies took us back in time and all around the world," she said. "They made us laugh, they made us weep, and they made us grip our armrests just a little tighter.
"They taught us that love can endure against all odds and transform our lives in the most surprising ways," she added, "and they reminded us that we can overcome any obstacle if we can dig deep enough and fight hard enough and find the courage to believe in ourselves."
