After Josh Duggar confessed to his porn addiction and cheating on his wife Anna, his mother Michelle announced that her eldest son has checked in to a rehab facility to deal with his issues.

It was believed that Josh had entered Reformers Unanimous, a Christian treatment facility that his family supported. But according to a new Radar Online report, it is not sure if Josh is seeking treatment at the said facility.

Doubts were raised after eyewitnesses spotted Reformers Unanimous "students" visiting facility's affiliate, North Love Baptist Church, for a group meeting on 28 August, and noted that Josh wasn't a part of the group.

RU residents are also required to attend church services at North Love on Sundays. But again, Josh wasn't present.

"Josh definitely wasn't there," the onlooker said. "It was very strange."

Speculations are now rife that Josh could be housed in a separate facility in Paragould, after the family's private plane was spotted taking a trip on 27 August across Arkansas.

Josh has been staying away from media glare since May, when it was revealed that he molested five minors, including his two sisters, as a teen. However, in August he once again grabbed media headlines when the Ashely Madison's website was hacked and Josh was revealed to be one of its members.

He promptly issued a public statement apologising for cheating on his wife and admitted he was addicted to porn.

Last week porn star Danica Dillon too came out and revealed that Josh sought her out and paid her to have sex with him on more than one occasion. Josh contacted Dillon through a secret Facebook account he maintained where he has befriended local strippers as well as lingerie models.

In an interview with In Touch, Dillon claimed that Josh first met her when she was performing at a strip club.

"He showed up and told her, 'I'm a fan. I've followed your work for years,' and then offered to pay her $600 for lap dances," In Touch magazine's Adriane Schwartz said. "He then proceeded to ask her for sex and said he would pay her $1,500. She agreed, and he came to her hotel, and this was consensual sex, but everything turned violent and she was terrified of him."
