Mindy Kaling Secretly Gave Birth to Her Third Child, Daughter Anne, in February: Photo

Mindy Kaling celebrated her 45th birthday on Monday, June 24, by revealing she quietly welcomed her third child a few months ago!

The actress shared the exciting news in an Instagram post that featured her newborn daughter and her two other kids, daughter Katherine , 6, and son Spencer , 3.

"In late February I gave birth to my daughter, Anne. She’s the best birthday present I could’ve ever imagined," the TV star gushed. "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," Kaling concluded. "Thanks for all the birthday wishes!"

The Office alum didn't reveal who the father of the baby was, nor has she shared her other children's paternity.

In the social media upload, the mom-of-three also posted a photo showing off her pregnancy belly and a snap with her kids in the hospital.

Kaling's friends and colleagues flooded the comments section with their well wishes, with Reese Witherspoon writing, "Beautifully said 💗💗💗."

"Awww congratulations Mindy!!! And happy happy birthday! ❤️," penned Angela Kinsey , while Tan France commented, "Oh my gosh, Mindy, I’m so happy for you!!"

Kaling has been in the headlines lately due to her physical transformation , though some people thought her weight loss regimen was a bit too extreme.

"I just tell myself I have to do basically 20 miles a week of either hiking or running. And so that's been incredibly helpful to me," she spilled in an interview of how she dropped the pounds. "It's really a big commitment. It's hard with two kids that I wake up really early and I fit it in — and I basically live in workout clothes so I can get it in, get an extra mile in ."

Kaling also does strength exercises like lifting weights and sticks to a healthy diet.

"For me, at this point in my life, I feel like I know what I’m supposed to be eating — you know, more leafy green vegetables and keeping red meat to a minimum — and for me personally, I also try to keep dairy at a minimum," explained the Emmy nominee.
