Emily Blunt stopped by The Howard Stern Show in NYC on Wednesday, where she briefly addressed her tumultuous split from crooner Michael Bublé. The two dated for three years, from 2005-2008. In this week's interview, Howard brings up Michael, talking about what a great guy he is and how into each other the two seemed to be. As Emily agrees with him, Howard continues, "But that was heartbreaking. Because he was not faithful." You can hear Emily sigh on the audio before she says, "Well . . . I don't know if it was . . . I don't know, it's complicated. Now I'm going red!" Michael actually addressed the relationship himself during an interview back in March, when he said, "I was a jerk and I was careless and reckless with the hearts of women I was with." In Emily's case, though, this is the first time she's really commented on what happened. Listen to the full clip below.
