According to MSN Entertainment on Friday, Jill is still following the rest of her siblings on Twitter, with the exception of her newly-married sister.

While no one knows for sure why the two women are feuding, there is speculation that it might have something to do with a little old-fashioned sibling rivalry and jealously.

While there seems to be tension between Jill and her sister, her marriage to Derick Dillard is a completely different story.

Just recently, Jill's own mother Michelle Duggar gushed about the couple's "perfect" marriage.

According to Us Weekly last Monday, the Duggar family matriarch says that so far everything is going as planned and that Jill right now is concentrating on her pregnancy before she becomes a mother for the first time next spring.

She told the site, "They have their schedule already - they get up and off to work of Jill works on her studies. Sometimes she'll pop by our place since it's awfully quiet at her house. She's so used to studying with noise. Jill is preparing to be a midwife."

Jill and Dillard have been married since June.
