Emily Blunt beat out Amy Adams, Margot Robbie, Emma Stone and Rachel Weisz for the honor at the 25th Annual SAG Awards

A quiet victory!

Emily Blunt won the best supporting actress honor at the 25th Annual SAG Awards for her part in A Quiet Place. The actress, 35, beat out fellow nominees Amy Adams (Vice), Margot Robbie (Mary Queen of Scots), Emma Stone (The Favourite) and Rachel Weisz (The Favourite).

The British star — also nominated for outstanding performance by a female actor in a leading role for playing magical nanny Mary Poppins in Mary Poppins Returns — starred opposite her husband John Krasinski in the hit thriller and actually filmed A Quiet Place and Mary Poppins back-to-back.

After kissing Krasinski, Blunt, visibly shocked to have won her first SAG Award, made her way to the stage to deliver a sweet speech.

“Oh my goodness me. Guys — that truly has completely blown my slicked hair back,” she said. “Thank you so, so, so much. I am so moved and completely lost for words and unprepared. I am going to share this completely with my husband, John Krasinski, because the entire experience of doing this with you has completely pierced my heart. You are a stunning filmmaker. I am so lucky to be with you and to have done this film with you.”

“Thank you for giving me the part. You would have been in major trouble if you hadn’t,” she joked.

She also thanked the couple’s daughters Hazel, 4, and Violet, 2.

“Thank you to the two little poems in our life, our daughters Hazel and Violet, who will have to be at least 45 before they see this film,” she said. “Thank you SAG, I am so honored.”

Krasinski, 39, proudly stood up for his wife as soon as she was announced as the winner, remaining standing and clapping until she took the stage. When she finished her speech, Krasinski, who was visibly emotional, immediately jumped back up and applauded enthusiastically.

Speaking to PEOPLE’s editor-in-chief Jess Cagle last year, Blunt opened up about why she took the dark part.

“I think I’ve just been too jolly and magical for too long,” she said. “I just needed to go toward the darkness for a little bit. When John was approached about Quiet Place, I had just had our second child. I remember sitting there on the couch with our tiny newborn baby, and he said, ‘I just got sent this script.’ I went, ‘You have to direct that movie. That’s so cool.’ ”

The 2019 SAG Awards, hosted by Megan Mullally, are airing live on Sunday on both TBS and TNT.
