Mindy Kaling is now a mom of three.

Kaling shared the happy news on Monday, which was also her 45th birthday, writing on her Instagram page that she gave birth to a baby girl named Anne in February.

She continued to write that she is “so lucky I live in a place where I could do this by myself, on my own timeline” and thanked her followers for all the birthday wishes.

In her post, Kaling shared a photo of her three children, a photo showing off her baby bump and a sweet snap of her two kids piled onto what appears to be Kaling’s hospital bed.

Kaling’s announcement came as a surprise, as the “Mindy Project” actor had not previously announced that she was expecting.

Her newborn daughter Anne joins siblings Katherine, 6, and Spencer, 3.

In March, Kaling said in an interview with Today that her two eldest children have already developed a close relationship.

The “Office” star has not been publicly linked to anyone and has not disclosed the identity of her children’s father(s).
