'Teen Mom 2' Leah Messer Cheating Husband Jeremy Calvert's Mistress Speaks! Find Out What 'The Other Woman' Has To Say About Leah Sleeping With Ex Robbie Kidd!

Teen Mom 2 star Leah Messer's husband Jeremy Calvert has been cheating on the reality star with a girl he met on social media, but now the other woman is defending herself against fans who are calling her a homewrecker.

"He told me they was separated, he filed for divorce!!" Brittany Musick wrote on a now-private Twitter account to all the haters.

She then went off saying, "F--k off you don't know the whole story!!" when one of her followers called her Jeremy's "piece of a--."

The reality dad's side piece then slammed the MTV star mom for being the cheater in the relationship, especially since Jeremy had blasted his wife on Twitter for sleeping with her ex-boyfriend Robbie Kidd behind his back.

"I liked him, I thought he was a great guy. && I'm not the home wrecker if anyone Leah is," she posted. "I just heard about their divorce, and he confirmed it. So why not talk to him and chill? You're never promised tomorrow."

As MStars News reported, little Adalynn's father wanted to have an overnight stay with the young beauty after he confirmed to her that he was now living in an RV. However, Brittany said she would never agree to spend the night with him.

"I don't have sleep overs. And wasn't gonna sleep over with Jeremy," she exclaimed.

This is a sudden about-face, especially since she admitted in her texts to the MTV star that she needed to stay over if they were going to meet up.

"Do I need to get a room or r u staying the night," Jeremy asked.

"Yea I prob would have to stay the night since I'm already getting there lil late," she replied.

In the end, all of the criticism and name calling from Leah's fans were too much for her.

"I will no longer be speaking to him. Leah can keep him," she said.
