America’s most famous super-sized family is growing again.

Jim Bob and Michelle Duggar, stars of the reality show “19 Kids and Counting,” are expecting their 20th child, the couple announced Tuesday on “The Today Show.”

The news comes almost two years after the arrival of their 19th child, Josie, who was born more than three months premature and spent several months in the hospital before coming home. Michelle Duggar said it was the longest she has gone without being pregnant in 20 years, and the family thought Josie might be their last child.

“We are so excited,” Michelle Duggar, 45, told “Today.” “I was not thinking that God would give us another one, and we are just so grateful.”

The Duggars 19 children all have names starting with “J,” and debates over the 20th baby’s name have already begun. The family will learn the baby’s gender around Christmas, and the newest Duggar will be born in April.

The family’s other children are Joshua, Jana, John-David, Jill, Jessa, Jinger, Joseph, Josiah, Joy-Anna, Jedidiah, Jeremiah, Jason, James, Justin, Jackson, Johannah, Jennifer, Jordyn-Grace, Josie.

The Duggars also have two grandchildren, Mackynzie, 2, and Michael, 4 months.
