Anna Duggar is finally ready to break her silence on husband Josh Duggar's scandalous behavior. Earlier this year, the star of TLC's now-canceled reality series "19 Kids and Counting" was accused of cheating on his wife using popular affair website Ashley Madison. Prior to that, it was revealed that he had inappropriately touched several young girls, a few victims being his sisters, at the age of 14. Anna, 27, has had little to say on the matter -- until now.

According to Us Weekly, the mother of four's comments will appear in her sister-in-laws' new TLC series "Jill & Jessa: Counting On." Clips from the show, previewed on "Good Morning America," suggest Anna will speak on the scandals early in the season. The short video shows her sitting in front of the camera alone sharing her initial reaction to the shocking news. Anna reveals to viewers that she was completely caught off guard by her husbands infidelity, adding that she'd been hopeful she would wake up the following day and everything would be back to normal. She said, at the time, she didn't want to believe it could possibly be true.

"I was just like, 'I'm gonna wake up and this is going to be okay,'" she said. "'And this really. This can't be true.'"

Josh's sisters, Jill Dillard and Jessa Seewald, will also open up about his involvement in the Ashley Madison scandal on the show. The newly released preview includes harsh comments from Jill, 24, suggesting that Josh, 27, was wrong to allow her and Jessa, now 23, to defend him knowing he was hiding more secrets. Earlier clips, released Nov. 20, show Jill assuring viewers that no matter how bad things seem, she and her family "will come out of this fire."

Despite Anna's initial denial, the scandal was very real. Since the story broke in August, adult film star Danica Dillon has come forward with allegations that Josh assaulted her during a sexual encounter. She said he approached her at a strip club, telling her he was a big fan. Josh is said to have offered her a large sum of money in exchange for sex, but Dillon's claims that once they were alone inside his hotel room, his demeanor changed. She recalls him being very rough, to the point that she felt as though she was being raped.

Josh, the eldest of Jim Bob and Michelle Duggar's offpsring, has admitted to being unfaithful. He released a statement in August in which he called himself the "biggest hypocrite ever." Josh came clean about cheating on Anna, chalking it up to an addiction to pornography. He told fans he was "so ashamed" before acknowledging all the people his infidelity had pained. Days later it was reported that Josh had sought treatment at Reformers Unanimous, a faith-based rehabilitation facility in Rockford, Illinois. Those reports remain unconfirmed.

"Jill & Jessa: Counting On" premieres on TLC on Sunday.
