"I was pretty blown away and I think he was just overjoyed," the actress told reporters of winning the acting award for A Quiet Place, which her husband John Krasinski directed

Emily Blunt says she was once warned against working with her husband — but it’s paid off in troves.

The actress, who was awarded the best supporting actress honor at the 25th Annual SAG Awards for her part in A Quiet Place, opened up about acting alongside and being directed by John Krasinski, who both helmed and starred in the horror film.

“My favorite thing about shooting A Quiet Place for sure was working with John,” Blunt, 35, told reporters in the SAG press room after her win. “We had never done it before and it is kind of the great unknown.”

She continued, “You go into this process not knowing what it’s going to be like. A lot of people were like ‘You’re going to be divorced by the end of it,’ but we were so much closer. I think the discovery of how we collaborated and could create something together was just so special.”

The British star — who was also nominated for outstanding performance by a female actor in a leading role for playing magical nanny Mary Poppins in Mary Poppins Returns — was visibly shocked to have won her first SAG Award on Sunday.

“Oh my goodness me. Guys — that truly has completely blown my slicked hair back,” she said during her speech. “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.

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.

Asked in the press room about Krasinski’s “state of mind” during her acceptance, Blunt teased, “I’m going to have to ask him.”

“He probably was as shocked as I was because I think it was very unexpected and it’s an incredible category and it’s certainly not something I had planned for,” she elaborated to reporters. “I was pretty blown away and I think he was just overjoyed. He was overjoyed.”

For the awards, Blunt wore a custom sparkling pink Michael Kors Collection gown accented with big satin ruffled shoulders. Krasinski looked sharp in a forest green suit and tie by designer ISAIA.
