Josh Duggar's porn addiction has not only brought disgrace to his religious family, but also to his wife Anna who is raising four of their children. After the 19 Kids and Counting star's name surfaced in the infamous Ashley Madison hack, the 27-year-old has now been accused of having sex with porn star Danica Dillon while his wife Anna was pregnant with their daughter Meredith.

The adult actress has alleged that the disgraced Duggar son had indulged in "unprotected and rough sex" with her, though she said that it was consensual.

"He walked into the Gold Club like a normal patron and said he'd been a fan for a long time and has watched my career grow — he even said from before my b**b job until recently — and that he loved watching my very first scene on [an adult website]. Then it got creepy," the porn actress, whose real name is Ashley Lewis, told In Touch.

According to the magazine, Dillon claimed that the father-of-four spent $600 (£387) for private dances and had allegedly asked her to "spend an evening with him".

"He was manhandling me, basically tossing me around like I was a rag doll. It was very traumatic. I've had rough sex before, but this was terrifying," the bisexual X-rated artist said about their sexual encounter. However she admits that she "took the opportunity because Josh offered to gift [her] $1,500". And as soon as Josh arrived at her hotel room, "things got rough", she claimed.

Now, the eldest Duggar son has been sent to rehab by his parents Jim Bob and Michelle who claimed "[We] were deeply grieved by our son's decisions and actions".

"Josh checked himself into a long-term treatment center. For him it will be a long journey toward wholeness and recovery. We pray that in this he comes to complete repentance and sincere change," the family wrote on their official website.
