John Krasinski and Emily Blunt have welcomed their second child into this strange, strange world! The Hollywood couple announced Baby No. 2 with a tweet on Krasinski's account.

In the celeb world, it's always hard to keep babies a secret, but Blunt and Krasinski managed to pull it off and announce on their own terms (in May, news finally bubbled to the surface that Alexis Bledel and Vincent Kartheiser had been new parents for months without anyone knowing). Krasinski is a big supporter of the No Kids Policy, a campaign started by Dax Shepard and Kristen Bell that urges paparazzi not to take pictures of minors and publications not to buy those photos.

In May of 2014, the couple announced the birth of first child Hazel. And now Hazel will be big sister!

Krasinski and Blunt began dating in 2008 and were married in 2010. In January, a rep confirmed that Blunt was pregnant with their second child.

Congrats to the two actors!
