Chelsea Houska and Kailyn Lowry quickly reacted to news of receiving a letter of Cease and Desist from their "Teen Mom 2" co-star, Jenelle Evans, earlier this week on Twitter. Now, after both women revealed they have no real interest in speaking of Evans, Houska's father, Randy, has spoken out against Evans, revealing that the mother of three has continued to share gossip about her co-stars, despite not wanting them to speak of her publicly.

“One day later, and all I can think is, ‘What the hell were they thinking that we would all shudder and cower to a stupid letter?’” Randy Houska wrote on Twitter, according to a report by In Touch Weekly magazine on November 29.

“Think ahead a couple of steps before acting,” he added to Jenelle Evans.

Randy Houska went on to tell Jenelle Evans to “cease and desist this” as he posted a screenshot of her recent post on Facebook, which included a photo of Aubree Houska along with an article about an alleged bombshell announcement on Instagram.

After receiving a letter of cease and desist from Jenelle Evans on Monday, Chelsea Houska took to Twitter to explain her thoughts on the issue, claiming that while she was accused of making false and defamatory statements against Evans, she never actually did so. Houska then told her fans and followers that Evans once claimed she was on drugs.

Kailyn Lowry also reacted to her letter on Twitter, telling fans that she is allowed to have an opinion, just as everyone else does, when it comes to Jenelle Evans' behavior on the show.

Chelsea Houska and her co-stars have been targeted by Jenelle

In addition to the recent photo shared by Jenelle Evans of Aubree, the reality star recently took aim at Chelsea Houska through re-tweets in which she showed that Houska's life at home with her husband, Cole DeBoer, and her two kids, eight-year-old Aubree and 10-month-old Watson, wasn't as perfect as MTV made it seem.

Evans then took aim at the network for making her life seem as if she had nothing but problems at home with husband David Eason and her three kids, including eight-year-old Jace Lewis, three-year-old Kaiser Griffith, and 10-month-old Ensley Jolie Eason.

Chelsea Houska and her co-stars, including Kailyn Lowry, Jenelle Evans Leah Messer, and Briana DeJesus, are currently in production for the upcoming season of MTV's "Teen Mom 2." No word yet on a premiere date for the new installment.
