Chelsea Houska appears to be fairly amused -- and confused -- about the legal letter she recently received from her "Teen Mom 2" co-star, Jenelle Evans. After opening the letter on Monday (Nov. 27), Houska took to Twitter to reveal that she had received a letter of Cease and Desist from Evans, even though she doesn't even talk about her.

Right away, fans wanted to know what had happened and questioned Chelsea Houska about the allegations being made by Jenelle Evans. In response, Houska said in a November 27 tweet that Evans was accusing her of making "false and defamatory statements" against her [VIDEO], which she never did.

"Who knows?" Houska tweeted.

Kailyn Lowry also received a cease and desist letter

Evans also targeted Kailyn Lowry with a letter of cease and desist [VIDEO] and in turn, Lowry fired back, saying that if she comments on Evans' role on "Teen Mom 2," it is her own opinion. She also reminded her fans and followers that Evans once shared her phone number with her thousands of followers on Twitter. However, despite the shocking moment, Lowry took no action against her co-star.

Chelsea Houska's personal life is quite happy

As Jenelle Evans continues to face allegations of abuse, Chelsea Houska's home life with husband Cole DeBoer is thriving. In fact, the couple recently celebrated their one-year marriage with a second wedding in South Dakota. As "Teen Mom 2" fans will recall, the couple initially got married in October of last year, just months after Houska confirmed she was pregnant with their first child.

Houska is also mom to eight-year-old Aubree from her past relationship with Adam Lind, who no longer appears on "Teen Mom 2."

Chelsea Houska and Cole DeBoer seem to have a great relationship on "Teen Mom 2" but in recent posts re-tweeted by Jenelle Evans on Twitter, their at-home life may not be seen accurately on the show. As Evans' re-tweets explained weeks ago, MTV acts like Houska is a perfect saint with no problems at all as they continue to suggest that Evans has all sorts of problems in her life at home with David Eason. "It's so obviously unbalanced I get they want more drama for ratings but it seems so edited and not true," the message from a fan read.

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.
