It looks like the problems between Jessa and Jill Duggar are getting even worse. Despite the fact that Jill recently posted a "happy family" photo with her sister and their husbands Ben Seewald and Derick Dillard recently, it looks as though the two newlyweds are still feuding behind the scenes.

According to Radar Online on Thursday, things have gotten so bad between the sisters that they will "have to sit at opposite ends of that long table during Christmas dinner" this year.

An insider told the site, "This has been brewing, and now that the girls and their marriages have become a bigger focus of the show, the problems are escalating."

Apparently, Jill is considered her family's favorite daughter while Jessa has been hitting back with sarcastic comments. The two have been fighting for the spotlight not only in the headlines, but at home with their parents Michelle and Jim Bob, too.

The source continued, "Jessa resents that Jill is her parents' favorite, and she's pulling away from the family. And Jill doesn't approve of the choices Jessa is making."

What's more, Jessa is distancing herself from her family while Jill is remaining close to her parents.

"Jessa is able to live for herself now, without the crazy rules - and she is learning who she wants to be - but Jill stayed pretty much the same when she left home," the source added.

So far, neither Jessa nor Jill have made any comments about their rumored feud.
