It’s a girl for Mindy Kaling!

The Mindy Project creator and star, 38, has welcomed her first child, a daughter named Katherine on Dec. 15, E! News reports. A rep for Kaling did not immediately return request for comment.

The actress’ pregnancy news first broke in July but it wasn’t confirmed until a very famous friend of the star spilled the beans: Oprah Winfrey.

On The Ellen DeGeneres Show in October, Kaling revealed that she was expecting a girl and dished on what it was like to have none other than her A Wrinkle in Time costar confirm the baby news.

“She did announce it,” the Champions creator told Ellen DeGeneres, stifling a laugh. “If anyone is going to announce big news about your private life, Oprah Winfrey is the person. You can’t complain that much about it. And you also can’t be like, “Hey, Oprah, zip it’ — because she’s almost like a religious figure.”

The pregnancy was “an unexpected surprise,” an insider told E! News, which first reported the news. Shortly afterward, a source revealed to PEOPLE that Kaling had “just started telling her friends” about her little one on the way — and was staying mum on the identity of her baby’s father.

“She is not telling anyone, not even close friends, who the father is,” said the source, adding that the then-mom-to-be was not dating anyone at the time.

At the September party for the final season premiere of The Mindy Project, Kaling’s costars had nothing but supportive things to say about their showrunner becoming a mother. “She’s going to be the greatest mom in the world. I am just so happy for her,” Beth Grant, who plays Beverly, told PEOPLE.

“She’s such a fearless leader, and she’s so strong, and smart and intelligent,” added Rebecca Rittenhouse (Anna). “I want her to be my mom, because she’s so incredible. But I will settle for her being my friend.

Kaling, 38, confessed that she was nervous about impending motherhood but hopes to be the “fun” mom during an interview with Willie Geist for Sunday Today in September.

“I’d like to be the fun mom,” The Office alum and two-time memoir author told Geist in her first interview about her baby on the way. “I know I’m gonna be the dorky mom. So it could be kind of fun too. I think that would be nice.”

In November, Kaling shared the first photo of her baby bump on Instagram to celebrate her last recording session for the sixth and final season of The Mindy Project on Hulu. Since then, the star has only shared glimpses of her growing belly, but has been snapped out and about in L.A. in adorable maternity attire.

In her September interview with Geist, Kaling also said she is planning to look to her own mother, who died of pancreatic cancer in 2012, for inspiration for her parenting style.

“My mom was incredibly fierce and so devoted to us, just loved us and really wanted us to be happy no matter what we did,” explained the Ocean’s Eight star.

“My career choice was not something that she was familiar with and she was just so supportive of that. And if I could give that to my child, just the open-mindedness, I’d be so happy.”
