Leah Messer is not on the best of terms with the mother of her boyfriend’s children, that according to her beau T.R. Dues’ ex, Mandy Winnell. According to the mother of two, Leah, who stars MTV’s “Teen Mom 2,” has not been accommodating to T.R. when it comes to parenting his two sons.

“She won’t let him come into my house anymore to drop off or pick up our sons,” Winnell told Radar Online of Tyshawn, 8, and Angelo, 4. “He has to let them out of the car and watch them walk to the door!” 

Winnell claims she used to have a strong co-parenting relationship with T.R., an athletic trainer, before Leah came into the picture in June 2015. Winnell says Leah, who has three daughters from previous relationships, feels “threatened” by her and thinks its “disrespectful” they exchange the children in a non-public place. 

After “ruining” her bond with T.R., 32, Winnell says she has plans to confront the 23-year-old reality star, whom she has labeled as "childish" and a "little girl."

“The father of my children and the friendship he and I have has nothing to do with that little girl,” Winnell said. “I have to be involved with him, whether she likes it or not. She’s so unbelievably childish I can’t stand it!”

Not only does Leah have what appears to be an impending conversation with Winnell on her plate, she is also fighting for custody of her 6-year-old twins, Ali and Aleeah. Leah’s ex-husband Corey Simms was awarded primary custody of the girls’ in August 2015. Two months after the hearing, Leah revealed her plans to get the courts to review their custody arrangement and said she is seeking 50/50 custody. The former couples are reportedly due to appear in court Jan. 27. 

Leah also shares 2-year-old daughter Adalynn with ex-husband Jeremy Calvert.

“Teen Mom 2” was speculated to have been renewed for a seventh season last year, though it's unclear if Leah will return.
