Jim Bob and Michelle Duggar, the couple at the center of the TLC reality series "19 Kids and Counting," are expecting their 20th child, Us Weekly reported Monday.

In a post on the Duggar family website, 45-year-old Michelle Duggar wrote, "Our whole family is so excited that God has blessed us with another child. Each one of our children are thankful to be here!"

The Duggars' 20th child is due in April.

The Tontitown, Ark., family's reality series premiered in 2008 as "17 Kids and Counting," and revised its title as their brood expanded. Their eldest child, 23-year-old Joshua Duggar, welcomed a second child of his own in June.
