John Krasinki and Emily Blunt got married in 2010 after dating for two years. The two seem to really adore each other ever since they first met. The couple now lives in New York with their two children, Violet and Hazel after staying in Los Angeles for years.

It was love at first sight according to John Krasinski, "It was one of those things where I wasn't really looking for a relationship and I was thinking I'm going to take my time in L.A. Then I met her and I was so nervous. I was like, 'Oh god, I think I'm going to fall in love with her.' As I shook her hand I went, 'I like you.'"

And though their first date location which was in a gun range was a bit weird for Emily, everything seemed to have gone better that expected.

But what about John's secret obsession?

Emily Blunt was interviewed by E! about her upcoming movie "Girl on the Train," however the interview got sidetracked into talking about John Krasinski. She admitted that John Krasinski is obsessed with the movie "The Devil Wears Prada" and when they were still dating, he had seen the movie seventy-five times.

"He's kind of stalkery like that. It's a little weird." Emily Blunt teased. "No, I'm touched and honored. He knows every single one of Anne Hathaway's outfits down pat."

She recalled, "I remember it came on one time when we first started dating and he was watching the montage where she has all the different amazing outfits, when he was watching he goes, 'And that's my favorite outfit.' I was like, 'Get a grip.'

John does know a good movie when he sees one. Good thing, Emily Blunt has taken John's long held obsession with a sense of humor.

"Girl on the Train" premieres in theaters on October 07.
