After being asked if her fiance Tyler Baltierra's father, Butch, was currently living with them, the Teen Mom OG star explained Butch was no longer eligible for parole, after he was involved in a knife fight behind bars.

"He was supposed to go to a program but he got attacked last time he was in the program. He got stabbed and, like, a bunch of stuff," Lowell revealed to OK! Magazine in a video interview on Monday. "So, he is not getting out at the moment. We are waiting to see if he can possibly get out soon, and if so, depending on him and his actions, we might let him stay with us for a little while. We will see."

Also in her interview, Lowell discussed her new baby, daughter Novalee Reign, born Jan. 1, 2015. On the show, Lowell's fiance expressed his disappointment in the child not being a boy, but nowadays, confirmed Lowell, Baltierra is perfectly happy with their little blessing.

"He's totally over it now. Just yesterday, he said, 'You know at first I really wanted a boy, but now I couldn't picture my life any different,'" Lowell recalled. "Plus, she's only two months old and already loves her daddy."

As for the child's birth, fans won't be seeing it on the show, unless they enlist Lowell's own footage, which she confirmed to have taken.

"The hospital wouldn't let them, but I probably wouldn't have let them either, honestly," she said.
