Josh Duggar sex scandal

Josh Duggar appears to have had an errant adolescent period and has accepted the molestation charges against him.

The 27-year-old reality star has drawn sharp criticism again after a video resurfaced on YouTube where he can be seen joking about an incest date.

The clip shows Josh joking about sibling dating between twins Jana and John David. The video of the eldest Duggar son was shot in 2008 when the popular family reality series was called 17 Kids And Counting.

In the clip, Josh can be seen explaining why he needed to find another couple to double-date with him and then-fiancée Anna.

"Ginger was chosen to be our chaperone and then she had to be pulled off because the movie we were going to see has to be over 18," the now father-of-three said to the camera.

"So, we chose Jana and John David – we thought why not, have a double date," the Duggar son continued and jokes about sibling dating. "We are from Arkansas!" he added.

The network stopped airing the show on 22 May but there are chances that the series might be back on soon as it has not been officially cancelled.

However, TLC will have to find sponsors as major advertisers including General Mills, have started pulling out of the controversial reality show about the evangelical Christian family.

ET Online suspects that TLC network, which has pulled its super hit series off air after the sexual molestation scandal, may fire the Duggar son and continue airing the rest of the current season as the show is popular for the daughters, Jana, Jessa, Jill and Jinger.

Jill has recently delivered a baby son Israel David, while Jessa is four months pregnant with her first child with husband Ben Seewald.

Josh, meanwhile, continues to retract himself from the public glare and has shut down his and Anna's official website. He has already cancelled his appearance at a Christian homeschool convention in Sandusky, Ohio.

The 27-year-old reality star had reportedly molested five underage girls, including some of his own sisters, when he was around 14 years old. However, the 19 Kids And Counting star has said he is 'sorry' for his inappropriate behaviour.

His parents Michelle and Jim Bob Duggar have apologised for their son's past mistakes on their official Facebook page.
