Jenelle Evans doesn't have a fan in her sister-in-law, Jessica Eason Miller.

According to a new report, the Teen Mom 2 star was recently targeted by the sister of her husband, David Eason, who went on an elaborate rant against the mother of three on Instagram after sharing a throwback photo of David with his nieces and nephews.

“[Seven] years ago!” Jessica began her rant, according to a Dec. 28 report by In Touch Weekly magazine.

According to Jessica, David has 10 nieces and nephews and has become known as "Uncle David" to many. However, this Christmas was far different from past years because David has reportedly stopped seeing her and her family as much in the years since his relationship with Evans began. As she told her fans and followers on Instagram, her children went from seeing their uncle nearly every day to rarely seeing or hearing from David at all.

She then blamed Evans, who is currently estranged from her own family, for keeping David away from his own loved ones.

“Our family has never been through anything like this before; we've always been strong,” she continued, “but, David's always had a good woman by his side. Not one that promotes hatred and is scared she'll be alone [because] she has no family."

According to Jessica, she still welcomes Evans to spend time with her and her family but admitted that not many members of their family like her anymore. That said, Jessica said that if Evans were to change herself and "defrost" her heart, that could change.

"This is effecting [sic] more than just one person. It's a shame, and a waste of precious time,” she added.

Jessica's latest rant against the reality star is one of many. In fact, earlier this month, Jessica took major aim at Evans by calling her a "sl*t" and suggesting that she had purchased 1,000 shares in 25 abortion clinics. Jessica also said that Evans has her own room at half of the abortion clinics.

To see more of Jenelle Evans, her family, and her co-stars, including David Eason, Kailyn Lowry, Leah Messer, Chelsea Houska, and Briana DeJesus, tune in to the upcoming season of Teen Mom 2 when the show returns to MTV next year.

A premiere date for the upcoming season has not yet been confirmed by MTV.
