Tina Fey Welcomes Daughter Penelope Athena

Tina Fey, already mom to 5½-year-old Alice Zenobia, has introduced a new addition to the family.

The 30 Rock star welcomed a healthy baby girl, Penelope Athena, on Wednesday, Aug. 10 with her composer husband Jeffrey Richmond, 51, her rep tells PEOPLE.

The Bossypants author, 41, first revealed her pregnancy to Oprah Winfrey in April.

Fey spoke about agonizing over having a second child – but explained how she and Richmond decided it was time to expand their family.

“My husband and I really decided that we felt rather than risk having 30 Rock end in several years and feeling like part of our family is missing that we were going to prioritize our family.”
