Josh entered a faith-based rehab program in August 2015, after admitting to being "unfaithful" to his wife Anna following a data leak for the cheating website, Ashley Madison, in which he was implicated.

A source told ET in December that Josh and Anna had remained in contact during his rehab stay, and were writing love letters to each other.

Anna blogged about visiting Josh in January, explaining, "It was an important step on a long difficult road."

"2015 was the most difficult year of my life. Yet, amazingly I've found that in my own life crisis God has drawn near to me ("He's near to the brokenhearted" Psalms 34:18) and my faith has been more precious to me than ever before," she wrote at the time. "Please continue to pray for me, Josh and our children."

Meanwhile, in February, TLC announced they were picking upJill and Jessa: Counting On for a full season. The network had previously canceled19 Kids and Counting after Josh admitted to molesting five young girls as a teenager. Anna will be featured on the show, as well as Jana, Jinger, Joy Anna, John David, Josiah and Joseph Duggar.
