Emma Stone wins second Oscar for best actress, with a slight wardrobe malfunction: Watch

Emma St(one)? More like Emma S(twice!)

Emma Stone won the best actress Oscar Sunday night for her role of Bella Baxter in Yorgos Lanthimos' "Poor Things," her second in the category.

"My dress has broken," Stone said, looking shocked as she accepted her gold statue. "I think it happened during 'I'm Just Ken,' I'm pretty sure," she added, poking fun at her "La La Land" co-star Ryan Gosling's performance. (Stone won her first Oscar for that film.)

She thanked the five former best actress winners who presented the category — Michelle Yeoh, Jennifer Lawrence, Jessica Lange, Charlize Theron and Sally Field — as well as her fellow nominees Lily Gladstone, Sandra Hüller, Annette Bening and Carey Mulligan. Stone and Gladstone had been neck-and-neck in the awards race; Gladstone would have been the first Native American actor to win a competitive Oscar.

Stone broke down her attempt to quell her shock in case she indeed won the award this year: "The other night, I was panicking, as you can kind of see happens a lot, that may be something like this could happen. And Yorgos said to me, 'Please take yourself out of it.' And he was right, because it's not about me. It's about a team that came together to make something greater than the sum of its parts. And that is the best part about making movies, is all of us together."

After thanking the cast and crew of "Poor Things," she gave her family a shout-out, including husband Dave McCary and their almost 3-year-old daughter.

"Most importantly, my daughter, who's going to be 3 in three days and has turned our lives technicolor, I love you bigger than the whole sky, my girl," she said, perhaps invoking song lyrics from friend Taylor Swift.

"Poor Things" nabbed several other trophies on Oscar night, including best costume design, production design and makeup and hairstyling, though fellow nominee "Oppenheimer" took home best picture, director, actor and supporting actor, among other awards.
