Olivia Colman was The Favourite at the 91st Academy Awards as she picked up the Oscar for best actress, with many praising her 'hilarious' acceptance speech.
The British actress was a surprise winner for her role as Queen Anne in The Favourite, beating the expected winner Glenn Close, who was hoping to win her first Oscar in seven nominations for The Wife.
Instead, a stunned Colman took the stage and said: "It's genuinely quite stressful. This is hilarious. I got an Oscar."
The British actress, who made her name as Sophie in Peep Show, consolidated Close in her acceptance speech.
She said: "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."
Speaking backstage after her win, Colman was asked where she will be putting her trophy.
She told the Press Association: "In bed with me, between me and my husband."
Former Peep Show co-star David Mitchell lead tributes to Colman's victory, commending her "brilliant" speech.
Mitchell tweeted: "Oh my God! That's amazing! And what a brilliant speech!"
Piers Morgan commented on the speech: "Nobody gives better speeches than Olivia Colman. Hilarious."
Fellow Oscar winner Julia Roberts took to Instagram to share her appreciation for Colman, writing: "I (love) Olivia."
Edgar Wright, with whom Colman worked on the film Hot Fuzz, said he is "so, so happy" for Colman, also sharing a photo of her in his 2007 film swinging a 'caution wet floor' sign, with the caption: "Colman takes out the competish."
Actress Olivia Munn commended Colman's performance for the Oscar, tweeting: "OLIVIA COLMAN was soooo amazing in The Favourite."
Colman was widely praised for her speech, in which she thanked her mother, father and her "kids who are at home and watching" before joking: "Well, if you're not, then, well done, but I sort of hope you are. This is not going to happen again."
Colman added the Oscar to her earlier wins at the Golden Globes, BAFTAs and National Society of Film Critics for the role.
The other nominees for best actress were Yalitza Aparicio for Roma, Lady Gaga for A Star is Born and Melissa McCarthy of Can You Ever Forgive Me?
