Lakshmi, 39, is pregnant with her first child after struggling for years with endometriosis, a condition that occurs when tissues that line the uterus grow outside the uterus, resulting in painful menstrual cycles and uterine scarring that could lead to infertility. The baby's father has not been identified and no other details were available.
Over the years, Lakshmi has spoken out about endometriosis and, earlier this year, she co-founded the Endometriosis Foundation of America to bring awareness to women who suffer from the same reproductive health issue.
"I'm somebody who never knew I had this condition and always thought that everything was okay," the Top Chef host told PEOPLE in April. "I found out in a very hard, difficult way – and I had to be operated on. Now, I'm fine but it was a very trying ordeal."
Lakshmi was previously married to celebrated author Salman Rushdie, but the pair divorced in 2007.
The news was first reported by US Magazine.
