It seems that Krasinski is happy to listen to his daughters, especially when it comes to his facial hair. He was rocking a beard during his appearance on the talk show, which he originally grew out for his new film A Quiet Place, a new thriller that he also directed and stars in alongside Blunt, 34. “They love it,” the actor said of his daughters’ opinion on the beard. “I thought they’d be terrified, but when I shaved it after the movie — in the movie, I have the beard — my 3-year-old said, ‘What happened to the beard?’ I said, ‘I shaved it. It’s so smooth, you can touch it.’ She went, ‘Put it back.’ ” Although Krasinski joked “I’m not a LEGO guy, I can’t just snap it back,” he clearly took her advice.
