When Katherine Heigl announced she was pregnant with baby number three, the 37-year-old star went into full (self-admitted) control-freak mode, even planning every detail of her baby shower down to the pristine-yet-rustic cake which celebrated the family’s Utah mountain home, where the babe was set to be born. But now it’s time for the wonderful chaos to begin, as Katherine has just welcomed a little baby boy into the family.

Joshua Bishop Kelley Jr. came into the world on Tuesday, December 20 (yep, he arrived nearly a month ago!), joining his big sisters, eight-year-old Naleigh and four-year-old Adalaide.

Back when the family first revealed they were expecting an addition, it was obvious that they were more than just a little giddy, with a rep telling People, “Naleigh and Adalaide could not be more excited to welcome their new sibling into the fold, and Josh and I are overflowing with joy and gratitude.”

We can’t wait to see pics of this family of five together, all smiles and cuddles.
