Josh and Anna Duggar are following in the footsteps of his parents, Jim Bob and Michelle Duggar, by expanding their family even more. The couple announced they’re expecting their fourth child.

“We are so excited to announce...we're pregnant! #4andCounting #BlessingfromTheLord @joshduggar #19Kids,” Anna tweeted on Tuesday.

She then took to Twitter again on Wednesday to thank fans for the well wishes, saying “Every life is precious & a gift from God - we're so #blessed to have baby #4 on the way.”

Josh and Anna already have three children; Mackynzie, 5, Michael, 3, and Marcus, 18 months.

However, they’re not the only 19 Kids and Counting stars expecting a baby next year. Josh’s sister, Jill Duggar, announced she’s pregnant just two months after marrying her now-husband Derek Dillard in June.

Just last month, Jessa Duggar married her fiancé Ben Seewald at the First Baptist Church in Bentonville, Arkansas, exchanging vows in front of 1,000 guests.
