Tina Fey and her husband Jeff Richmond have welcomed a new addition to their family.
On Wednesday, the 30 Rock star gave birth to a healthy baby girl named Penelope Athena.
The little girl joins Tina and Jeff's five-year-old daughter Alice.
Tina chose not to find out the baby's gender during her pregnancy, joking earlier this year:
"We decided we are going to wait.
"We're going to find out…never. Not even after it's born, I'm just going to see what it chooses to wear to prom."
The 41-year-old announced the news of her pregnancy during a taping of Oprah in April.
The comedian said she has agonised over whether to have a second child – but explained how she and Jeff had decided to expand their brood.
"My husband and I really decided that we felt rather than risk 30 Rock end in several years and feeling like part of our family is missing that we were going to prioritise our family," she said.
