Welcoming a new addition to the family, Diablo Cody has announced the arrival of a healthy baby boy named Marcello!

The "Juno" screenwriter, who's married to Dan Maurio, tweeted the gleeful news of the baby's arrival on Tuesday (July 27).

The 32-year-old wrote, "We had our boy early this morning! Marcello Daniel Maurio, 7lbs, 2 oz, lightly mustachioed."
