Duck Dynasty‘s Sadie Robertson says she is “praying” for her friends amid Josh Duggar‘s second sex scandal.

“It honestly makes me really sad that they’re having to go through this, because it’s one thing to go through it as a family, and it would be just as hard for them if they weren’t in the limelight, but … everybody’s talking about it, and that just adds that many more comments, that many more opinions,” Robertson tells PEOPLE Now while promoting her new book Live Original. “We’ve been there, it’s hard.”

TLC had already canceled 19 Kids and Counting after Josh admitted to molesting five underage girls (including his sisters) as a teen, but the former conservative lobbyist fell from grace again after confessing to cheating on his wife Anna using the website Ashley Madison last week.

“It’s been kind of a secret for a long time, and everybody knows, when secrets come out, it’s not fun. Secrets are hard. You shouldn’t keep secrets,” says Robertson, 18. “At this point it is what it is, and so they’re just going to have to make the best out of it. … If they can forgive him, it will all work out.”

Robertson also remembers the backlash her own family faced following her grandfather Phil Robertson’s anti-gay comments.

“They almost canceled Duck Dynasty whenever my grandpa said the things that he said, and that would have been, in my opinion, not a very good decision, because that was putting one man’s words in all of our mouths,” she explains. “Josh Duggar, that’s not his whole family. His whole family didn’t do that. He made a mistake.”

Ealier this summer, Robertson’s uncle Jep opened up about being molested as a child.

“I was 6, and it was on a school bus, and it was an older girl,” he told Entertainment Tonight. “Back then the high school students would ride on the same bus as the grade school. There was an older girl that was just real mean. I think that she was just terribly abused herself. But yeah, it was a lot of things that took place – scary stuff. It was tough.”
