For Teen Mom's Kailyn Lowry, home's not necessarily where the heart is. In fact, it's where Lowry, 19, and her mom are most at odds.
In a new sneak preview clip from Tuesday's episode, the mother of 23-month-old Isaac worries that her mom -- and her boyfriend -- will evict her from their home even after inviting her to move in.
After she receives a note from her mother's boyfriend arguing that she "live[s] like trash," Lowry vents her frustration to a friend, taking offense that her mom didn't come directly to her first.
"My mom had to have known. If it was just my mom doing this in her own apartment, it would never be an issue. I'm so f--king furious with her," Lowry snipes in the clip. "Don't invite me to stay in your house if you're going to nitpick every single thing I do. I work two jobs, go to school full-time and have a kid. When I come home and straighten up my room, whatever straightening up I do to it should be good enough."
Lowry -- who lived with baby Isaac's dad, Jo Rivera, and his parents until an ugly spat left her out on the street and involved in a custody dispute -- says her relationship with her mom ended for good after their spat.
"She chose him over me," Lowry tells the new issue of Us Weekly. "That was the last straw; I haven't talked to her since."
