“Pics of kids should only come direct from parents. So I’m thrilled to introduce you guys to Hazel!!!!” he captioned the photo.

“Wanted to let the news out directly. Emily and I are so incredibly happy to welcome our daughter Hazel into the world today! Happy bday!” Krasinski wrote then.
Krasinski and Blunt tied the knot in 2010.
