John Krasinski burst into tears the first time he heard Emily Blunt sing

Want to feel as cool and in-the-known as John Krasinski for a second? Okay, so he, and I, and you, and everyone else were all let in on the same secret at the same time: Before starring in the movie adaptation of the musical, Into the Woods, John Krasinski had no idea that his wife of seven years, Emily Blunt, could sing. Same! So he, and I, and you, and everyone learned all at once that Blunt can belt it out, and chances are, upon learning this, you did not cry. But Krasinski did!

Apparently, Blunt and Krasinski, who are a very private couple, even manage to keep things from one another. Like, say, the fact that one of them can sing. In a new cover story in Vanity Fair about the soon-to-be Mary Poppins, Krasinski explains that when his wife first told him that she was going to be in a musical, he was worried. He was even frightened for her. But all it took was one trip to the recording studio to have all his fears dispelled.

"[I thought Emily and I were] at the same level of singing talent, which is low mediocre," he explained to the magazine. "I thought [Into the Woods] was such a cool gig, but, to be honest, I was really nervous for her.

That’s sweet, and precious, and is one of the reasons Krasinski + Blunt remain a favorite Hollywood couple — but Krasinski was still hesitant about his wife singing on-screen. He went to recording session for the film where he confessed to director Rob Marshall that he had “never heard her sing.”

“[Marshall] looked at me as if the earth had just opened up in front of him, Krasinski continued. “His mouth was wide open. He did not say anything. He just turned to the window, cued the song, the orchestra started playing, and Emily started singing, and I just immediately wept. It was really wild. It was like finding out that your wife can levitate. It was just like, ‘When were you going to tell me this?’"

Now we’re just waiting on Emily to tell us what happened the first time she heard Krasinski sing. Maybe she also cried…but possibly not in a good way?
