The “Knocked Up” actress (no pun intended) announced the birth on Instagram and her lifestyle website, www.thoseheavenlydays.com. She said she and Kelley are “full of high hopes and bubbling anticipation.” Heigl said she and Kelley were considering adoption again, fostering or pregnancy, if it was possible.

Kelley said on Instagram he “can’t wait to hold this little nugget.”

Heigl shot to stardom on the ABC hit “Grey’s Anatomy” and in movies like “Knocked Up” and “27 Dresses.”

She’s set to star as a defense lawyer in the upcoming CBS drama, “Doubt.”
