"19 Kids and Counting" alum John-David Duggar recently slammed his older brother Josh for the scandals he was involved in.

In the new teaser for "Jill & Jessa: Counting On," Duggar revealed how disappointed he was when he found out that his older brother cheated on Anna, and even more when he discovered that he sexually molested young girls.

"After everything started to settle down from the first release of stuff in the news about Josh, we got word of a second thing that we had no clue about," he said in the promo clip.

"That was a little bit more of a shock probably than the first stuff coming out," he added.

Meanwhile, Duggar said that he always looked up to his brother, and wanted to become exactly like him when they were still kids.

However, after Josh's recent scandals, Duggar said that he doesn't even want to be associated with him anymore.

"It's a big load. It's a big weight upon me now. I know that I've got a whole bunch of younger siblings looking up to me, and I've got to be an example to them. Because whatever I am, that's what they want to be. I know that's what it was for me and Josh. I always wanted to be like him. But one of the toughest things I ever had to tell my older brother was, 'I don't want to be like you anymore,'" he said.

Fans can hear the insights of the Duggar family members in the upcoming TLC spinoff starting Dec. 13.
