Leah Calvert opens up about her decision to receive therapy in a “Teen Mom 2” Season 6 clip, but she doesn’t confess to her rumored drug problem. In a sneak-peek video of the forthcoming season, which premiered during a “Teen Mom 2” catch up special, Leah and her ex-husband, Corey Simms, and his wife, Miranda, sit down for a heart-to-heart.

Leah, who shares 5-year-old twins, Ali and Aleeah, with Corey, starts the conversation by admitting she has some things she needs to work on. “I’m gonna need help with the girls,” Leah tells Corey and Miranda in the clip, which was first obtained by The Ashley's Reality Roundup. “I gotta do this, like, therapy. I guess, like, at a facility or something.”

Corey tries clarifies Leah’s comments, asking if she’s attending rehab. Despite reports Leah was released from Utah’s Cirque Lodge earlier this month for treatment for depression and drug issues, Leah denies she is planning to receive rehabilitation.

“It’s nothing bad,” she says. “I feel like me going there, I’m going to be able to be a better mom and be the best mom that I can be."

Miranda then asks Leah if her comments about trying to be a better mom is her “owning up” that she’s hasn’t “been able to be the best person" for her children. “I’m not gonna say I was a bad mom,” Leah says before going on tells the couple she has been dealing with a lot at home. Corey then asks if she has been taking something – alluding to drugs – to help her deal with her issues.

“We understand what you deal with,” Corey says. “We’re saying is there something that you take to deal with that problem? … Can you look at me and Miranda in our eyes and tell us there is no drug problem?”

“There is no drug problem,” Leah responds.

“I think I know that there’s a drug problem and I think you’re afraid to tell me. And I think that you’re afraid to tell me,” he says.

Corey accuses Leah of making up issues in order to cover up her alleged problem with drugs, telling her to stop “beating around the bush.” Leah responds, telling her ex, “shame on you.”

“As their father, I will do that I have to do,” Corey threatens. When Leah retaliates with a similar comment, Corey tells her to “start being a mom.”

“Teen Mom 2” Season 6, which premieres on MTV on July 9, will reportedly focus on Leah’s alleged drug issues and her martial problems with now ex-husband Jeremy Calvert. The duo reportedly finalized their divorce on June 8. They share one daughter, 2-year-old Adalynn.
