After a series of sex and cheating scandals, Josh Duggar was sent to rehab by his famous parents Jim Bob and Michelle. However, a recent sighting of the family's private plane at the Rockford airport, Illinois, has sparked rumours that the eldest son of the reality TV star couple may have joined his family in Arkansas.

According to a report by Rockford Scanner, the Duggar family plane was parked on the Rockford airport ramp on 11 November. Later, it took off around 2.30pm the same day and headed towards the family's hometown of Springdale Arkansas.

A Facebook page, which keeps criticising the family for their 'hypocrisy', has reported that the disgraced reality star will join his family for the Thanksgiving meal. However, the report also clarifies that they are not sure if one of the persons who boarded the plane was Josh or not.

"Not sure if he is in the plane or not. It could have just been a family visit. I don't think I would ever want to ride in that plane since the video shows them having trouble closing the door," Life Is Not All Pickles And Hairspray wrote on its Facebook wall with the embed video of the Duggar flight.

Here is the video:

The evangelical Christian family became hugely popular with their show 19 Kids
And Counting, for displaying high cultural and religious values and raising 19 children. However, during the last season of the super hit TLC reality TV show, the family came under fire after a series of revelations against Jim Bob and Michelle's 27-year-old son.

Josh was accused of sexually abusing his younger sisters Jessa and Jill when he was a teenager. This was later confirmed by his famous sisters who went on to defend their brother. Later, adding insult to injury, the Ashley Madison hack revealed that he allegedly had multiple profiles on various websites including Facebook and OKCupid. To add to the shocking revelation, porn star Danica Dillon claimed Josh had a violent sex affair with her.

Inquisitr reports that the father-of-four is attending the Reformers Unanimous Men's School of Discipleship in Rockford, which deals with drug and alcohol addictions. However, it also reports that the institute has no licensed therapists or medical professionals.

The Duggars, however, are yet to confirm Josh's homecoming. The family's Facebook page is currently gushing over Jessa's newborn baby Spurgeon Elliott Seewald.
