The couple shared the exciting news on their social media on Friday.
The former 19 Kids and Counting reality stars announced that they are expecting their sixth child together on their Instagram account on Friday.
"We are so excited to announce that we are expecting a new little one! As we watch our children grow and thrive — we look forward to baby six joining us this fall! #littleduggars," Anna, 30, wrote alongside a video that features their children laying out letters that spell out, "New baby coming this fall."
"Mommy is having a baby," Anna can be heard telling her youngsters as they scream in excitement. The couple—who tied the knot on Sept. 26, 2008 -- is already parents to five children: Mackynzie, 9, Michael, 7, Marcus, 5, Meredith, 3, and 19-month-old Mason.
The Duggar family's official Instagram also posted a pic of the expectant parents and their kids, captioning the sweet snap, "So excited to have another grandbaby due in November!! ?."
Josh's parents, Jim Bob and Michelle Duggar, also shared a heartfelt message on their website, congratulating the pair.
"We are so happy for Josh and Anna, expecting their 6th child and our 16th grandchild! Each child is a blessing from God! Anna is one of the most amazing women in the world, she is a Proverbs 31 woman!" the statement began. "Anna & Josh are good parents and it is going to be neat to see what God does with each one of their children’s lives. Mackenzie, Michael, Marcus, Meredith and Mason are so excited to have a little sibling on the way! God is at work in their sweet little family! He has blessed them with another child! What a gift! The best days for their family are still ahead!"
Earlier this week, Amy Duggar and husband Dillion King announced they were expecting their first child together. Additionally, Joseph and Kendra Duggar also revealed in early April that they too are pregnant with their second child.
