Mindy Kaling has given birth to a baby boy.
The 41-year-old star — who has two-year-old daughter Katherine — revealed the surprising news this week after welcoming her new bundle of joy into the world just over a month ago.
Appearing on The Late Show With Stephen Colbert on Thursday night (Oct 8), she said: "I gave birth to a baby boy on September 3.
"This is news to a lot of people... His name is Spencer."
Colbert noted people didn't even know she was pregnant, and Mindy is usually private about her personal life.
She previously opened up about her relationship with a baby nurse called Rose in her book Nothing Like I Imagined (Except For Sometimes), and admitted she wasn't sure if she'd have "another baby".
She wrote: "Rose helped me with everything. The fear of being alone with my baby. The fear of my baby not bonding with me. The fear of me not bonding with her. The fear of not being able to feed her...
"All these fears were the worst I've ever had in my life, and Rose helped me keep them at bay. She was my mom when I needed a mom, and that wasn't even her job...
"I told her I don't know if I'll have another baby, but if it meant she would come and live with me, I may just go ahead and do it."
Meanwhile, The Office and Mindy Project actress is yet to reveal the identity of her daughter's father.
She previously explained: "My feeling is that until I speak to my daughter about that, I’m not going to talk to anyone else about it.
"I think people are often surprised that for someone who seems as open as I am on social media and who writes things that seem drawn from my life, I find that stuff [her relationship with Katherine] really private." — BANG
