Mindy Kaling secretly had her third child in February

She captioned an Instagram post that featured photos of her new arrival - a girl called Anne - with her siblings Katherine, six, and Spencer: "She's the best birthday present I could've ever imagined.

"When things are hard, whenever I veer towards cynicism, my three kids are such a great reminder of the pure joy in my life."

"I'm so lucky I live in a place where I could do this by myself, on my own timeline. Thanks for all the birthday wishes!"

Mindy included a throwback snap of her baby bump with the post.

In 2020, the comic and actress announced on 'The Late Show with Stephen Colbert' she had given birth to Spencer without ever letting the public know she had been pregnant.

She said: "I'm telling it for the first time now... I gave birth to a baby boy on 3 September."

Mindy has never disclosed the father of her children, and left the box for the father's name on Katherine's birth certificate blank.

Fans have speculated Mindy's former boyfriend and 'The US Office' co-star BJ Novak, 44, is the father of her kids.

The duo dated on and off between the early years of making the American version of Ricky Gervais' sitcom in 2004 and 2007 and BJ is godfather to two of Mindy's kids.

Their 'Office' characters Kelly and Ryan had a complicated relationship on-screen, and by the series finale, the two characters were back together.

At the 2022 Emmy Awards, the pair poked fun at their "insanely complicated relationship" while co-presenting the award for writing for a limited or anthology series or movie.
