Days after revealing Josh Duggar has checked into faith-based rehab, the family celebrated his younger brother Josiah‘s 19th birthday.

“Josiah is creative and a hard worker,” the former 19 Kids and Counting stars wrote on their Facebook page Friday, sharing side-by-side photos of Josiah as an infant and all grown up. “We are especially pleased with the wonderful young man he’s become.”

Josiah, who is the eighth of Michelle and Jim Bob Duggar’s 19 children, made headlines in April when he began courting family friend Marjorie Jackson, but the couple ended things earlier this month.

Michelle, 49, shared her own message for her son as well.

Josh, 27, is embroiled in his second high-profile sex scandal: He confessed to cheating on his wife Anna after being outed in the Ashley Madison data dump Aug. 20, and in May he admitted to molesting five underage girls, including his sisters, as a teen.
