The British star appeared visibly shocked as Frances McDormand and Sam Rockwell announced she’d beaten The Wife's Glenn Close to the trophy.
She graced the stage and had the audience in stitches as she delivered what many believe to be the best speech of the evening.

“It’s genuinely quite stressful. This is hilarious. I got an Oscar! Okay, I have to thank lots of people. If, by the way, I forget anybody, I’m going to find you later and give you all a massive snog. Yorgos - my best director and the best film and with Emma and Rachel, the two loveliest women in the world to fall in love with and to go to work with every day. You can imagine this wasn’t a hardship. And to be in this category with these extraordinary women and Glenn Close – you’ve been my idol for so long and this is not how I wanted it to be and I think you’re amazing and I love you very much. I love you all. Thank you.
“Lindy King – my agent – who took me on over 20 years ago, thank you so much, and Olive and Hildy and Brynna, who made me do things I said no to, but she was right. And my mum and my dad – well, you know. My kids, who are at home and watching. Well, if you’re not, then kind of well done but I sort of hope you are; this is not going to happen again. And any little girl who’s practicing her speech on the telly, you never know. I used to work as a cleaner and I loved that job but I did spend quite a lot of my time imagining this. Oh, please wrap up [blows raspberry at the prompter].
“My husband, Ed, my best friend, I love you so much. 25 years and you’ve been my best supporter. He’s gonna cry! I’m not. Thank you so much – Fox, everybody, the cast and crew. Thank you. Argh, thank you so much. Lady Gaga! And Melissa! Thank you.”
Earlier in the evening, Rami Malek took home Best Actor for his portrayal of Freddie Mercury in Queen biopic Bohemian Rhapsody. Mahershala Ali won Best Supporting Actor for this year’s Best Picture winner, Green Book, while Regina King won Best Supporting Actress for her performance in If Beale Street Could Talk.
The films vying for success at this year’s ceremony included Alfonso Cuarón's Netflix drama Roma, the Bradley Cooper-Lady Gaga musical A Star is Born and BlacKkKlansman. The former led with 10 alongside Yorgos Lanthimos’s The Favourite, with Adam McKay’s political satire Vice following close behind with eight.
