'Teen Mom 2' Leah Messer's Sister Says They 'Have Hidden Truth' On Jeremy Calvert Amid Cheating Scandal!

Teen Mom 2 star Leah Messer has had tumultuous relationships on the show and may now be on the verge of divorce, but her family has always stood up for her. Just last week, the MTV star's husband Jeremy Calvert went on Twitter and accused her of cheating with ex-boyfriend Robbie Kidd — the same guy she cheated on her first baby daddy Corey Simms with. Leah went on to deny the allegations while Jeremy deleted the tweets, but now her sister Victoria Messer is standing up for her against her brother-in-law.

The reality sister went on Facebook to write, "You've wanted out of the marriage for a while and now your [sic] trying to make assumptions to make yourself look good to make people feel sorry for you.

"You wanna sit around and post a bunch of bulls--t but little do you know sweetheart, we are a little smarter than you are and we actually have proof of s--t that you've done," she continued in a veiled accusation to Jeremy. "So maybe you should think before you start making up lies because we have hidden truth."

According to Radar Online, Victoria went on the radio to defend her sister against Jeremy's hurtful messages.

"Just because it happened once does not mean it happened again," she said of Leah's cheating. "She would never."

Ali and Aleeah's aunt also got into a Facebook fight with Jeremy's cousin Christina Young. In the comments section to the post, the two hurled insults back and forth about each other's family.

Here's the exchange:

Christina: "You have really messed with the wrong family. & thats all im saying."

Victoria: "Sweetheart you have no clue who we are either, just saying!"

Christina: "Oh I know enough. & I know my family has morals unlike yours."

Victoria: "I feel bad for you because your [sic] sitting around defending people that sit around and talk s--t about you guys."

Christina: "Now youre saying my cousin talks s--t about me? Ha! Funny."
