"Emily and I are so incredibly happy to welcome our daughter Hazel into the world today! Happy bday," John wrote on his social network feed.

Emily revealed was expecting a girl after buying a trendy Aspen Custom Pink Velvet Regency Glider nursing chair and stool for $3,651(!).

The couple - who started dating in 2008, got engaged in August 2009 and got hitched in Italy last summer- celebrated the impending birth with a baby shower back in December, and invited pretty much the whole of Hollywood along.

Actresses Jennifer Aniston, Amy Adams and Kristen Bell were all there with presents, of course. "It was a very casual shower," an insider told People at the time."Emily seems very excited about the baby and looks great.

"She opened gifts of baby clothes and plush toys in front of her guests as they enjoyed cookies and chocolate. Everyone was oohing and ahhing."
