And baby makes three! Mindy Kaling secretly welcomed her second child last month. The Office alum announced the exciting news Thursday during an appearance on The Late Show with Stephen Colbert. “I’m telling it for the first time now, it feels so strange. But I gave birth to a baby boy on September 3,” she shared. “No one even knew you were pregnant!” host Stephen Colbert exclaimed, to which the actress replied, ”I know! I know! This is news to a lot of people. It’s true.”

As for her son’s name? “His name is Spencer,” Mindy, 41, revealed. “I forgot the most important part of it.” Ahead of her virtual appearance, the mom of two teased that she would be sharing “big news” on the show. “This is proof for when you catch me on @colbertlateshow tonight that I’m wearing pants. Join me as I talk to Stephen about my @amazon essay collection, Nothing Like I Imagined, and drop some big news!” she captioned a photo of herself modeling a pink Oscar de la Renta dress.

Spencer joins big sister Katherine. When asked how her two-year-old daughter received her little brother, the TV star admitted that Katherine “was very ambivalent at first.” “She was really worried about her toys getting taken,” Mindy explained. “She thought that it would be another child that was her same size, but then she was delighted when he arrived home with me at the hospital and he was just a blob who couldn’t take her toys. So, she’s a huge fan now that she’s met him.”

The Mindy Project alum, who welcomed Katherine in 2017, has kept her daughter’s paternity private. “My feeling is that until I speak to my daughter about that, I’m not going to talk to anyone else about it,” she told the New York Times in 2019.

Mindy admitted to Glamour last year that she’s always wanted to have children. She confessed, “I always knew I wanted to be a mom, but I would have put it off and put it off. I’m happy that it happened when it did. I would have put it off indefinitely. I’ve seen firsthand the heartbreak of women who have waited to get pregnant [and then it doesn’t happen]. For me, my relationship with my mother was such an integral part of my life. Thinking back on our relationship is still such a huge source of my happiness day to day, so I’m so grateful for having Katherine.”
