Kaling shared the news during an appearance on The Late Show with Stephen Colbert.
“I got something I rarely get these days, which is good news, so if you wouldn't mind sharing with our audience I think they'd be thrilled to find out something extraordinary that nobody knows up until this moment,” Colbert said during the virtual interview.
“Yes, I'm telling it for the first time now. It feels so strange,” Kaling replied. “But I gave birth to a baby boy on 3 September."
Colbert remarked how “no one even knew” that she was expecting, to which Kaling said: ”I know! I know! This is news to a lot of people. It's true.“
Kaling already has a two-year-old daughter, named Katherine. The comedy writer has never shared a picture of her daughter's face or the identity of the child’s biological father, saying it was important to maintain some privacy.
Explaining her decision during an interview with the New York Times in 2019, Kaling said: “My feeling is that, until I speak to my daughter about that, I’m not going to talk to anyone else about it.”
However, she has revealed her former The Office co-star BJ Novak is Katherine's godfather.
“The truth is that BJ is so much more like family now than a platonic friend,” Kaling told Good Housekeeping.
“He's the godfather to my daughter, he comes over like once a week. Sometimes he'll come over just to hang out with her.”
The Ocean's 8 star previously opened up about her decision to become a mother during an interview with Glamour in 2019.
“I always knew I wanted to be a mum, but I would have put it off and put it off. I'm happy that it happened when it did,” she said.
“I would have put it off indefinitely. I've seen first-hand the heartbreak of women who have waited to get pregnant [and then it doesn't happen].”
Kaling’s announcement comes just days after fellow actor Amanda Seyfried revealed she had given birth to her second child, after keeping her pregnancy a secret from the public.
The Mamma Mia star shared the news in a joint statement with her husband Thomas Sadoski to charitable organisations INARA (International Network for Aid, Relief and Assistance) and War Child.
“Since the birth of our daughter 3 years ago our commitment to the innocent children that are so brutally affected by conflict and war has been a driving force in our lives,” they said.
“With the birth of our son the work of INARA and War Child has become our North Star.”
