Zooey Deschanel and her fiancé Jacob Pechenik have welcomed their first child together and secretly tied the knot, according to Page Six.

Deschanel gave birth to a "beautiful healthy baby girl" last week in Austin, Texas where Pechenik, a movie producer, is based. The couple announced they were expecting in January and a week later, the "New Girl" star confirmed her engagement.

"Jacob and I are over the moon. We are so excited to meet our little one," she told People at the time.

Fox filmed extra episodes of Deschanel''s comedy for its upcoming season earlier this spring to accommodate her pregnancy. "New Girl" will premiere on Tuesday, Sept. 15.

The 35-year-old actress also welcomed a new nephew in June when her sister Emily Deschanel gave birth to a baby boy. It was the second child for the "Bones" star with her husband David Hornsby. They also have a three-year-old son, Henry.
