Amid the scandal, Anna celebrated the wedding of Josh’s cousin Amy Duggar to Dillon King alongside her in-laws Jim Bob and Michelle and the rest of the Duggar clan.

“I saw her before the ceremony and just gave her the biggest hug ever,” Amy tells PEOPLE of Anna. “That’s when I got the most emotional. She told me to have just an amazing day.”

Josh and Anna’s oldest daughter Mackynzie, 5, served as flower girl for the chic wedding at Horton Farms near Bentonville, Arkansas

Josh did not attend the ceremony. He is seeking treatment at Reformer’s Unanimous in Rockford, Illinois, a faith-based rehab center that’s reportedly helping him overcome his proclivity for infidelity and pornography, tension is brewing back at home.

While a source close to the family Anna’s parents, Mike and Suzette Keller, remain in Josh’s corner, he’s losing support from some of those closest to him.
