It's a busy time of the year for celebrity couples who are having babies left and right. After the announcement of Simon Cowell's baby boy at the end of last week, as well as Megan Fox and Brian Austin Green's son, it's now the turn of John Krasinski and Emily Blunt to inform the public.

The happy father wanted to make the news official as soon as possible and quickly took to Twitter to broadcast the news. “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!” he tweeted.

Emily Blunt, 30, thus brings into the world her first child, daughter Hazel, after she announced her pregnancy back in September last year, People is reporting today.

“The Office” actress and Krasinski have been married since 2010, after they dated for two years and, according to Blunt herself, were always planning on having kids. While they did take their time, the couple was elated at the birth of their new baby daughter.

“We want to have children; I just don't know when yet,” the actress said in an interview. “I'm just not sure about the timing of all of that. We're both from big families so I think it's something we want.”

A heavily pregnant Emily was thrown a baby shower in late December last year, which turned out to be quite the celebrity affair, with several big names in attendance. Among those who came to wish her well were Jennifer Aniston, Kristen Bell and Amy Adams.

At the time, the happy mother-to-be was reported to be enjoying herself immensely, as she was opening up gift boxes with baby clothes and plush toys and indulging on cookies and chocolate together with her guests.
