The Office star and his actress wife Emily Blunt welcomed their first child, daughter Hazel, in February (14), and the star took to Twitter.com on Tuesday (13May14) to share the very first photo of their bundle of joy, in which the tot is stretching her arms while laying in her bassinet.
He added the caption, "Pics of kids should only come direct from parents. So I'm thrilled to introduce you guys to Hazel!!! #NoKidsPolicy"
Krasinski and Blunt have joined the likes of Alyssa Milano and Minnie Driver, who have signed on to help Bell and her husband Dax Shepard raise awareness about their No Kids Policy campaign, which calls for a boycott of tabloids which buy in unapproved pictures of stars and their kids - in a bid to protect the youngsters from aggressive snappers.
