The young women of "Teen Mom 2" returned to MTV Monday night for the docu-series' season premiere. And as viewers quickly learned, the more things have changed, the more they've stayed the same for one of the moms.
Shortly after completing a month-long stint in rehab, Jenelle Evans confessed she'd fallen off the wagon.
"Well, you know, everything's been going great since I got out of rehab," she explained during the episode. "And then, you know, when I was with Marissa last night, like, I (expletive) up."
In other words, she got high.
"She was like, 'Well, do you want to smoke?' I was like, 'Well maybe one hit won't, you know, hurt,'" Jenelle said. "Then I was like, 'OK, one more.' And then I took three hits of weed, and then I was like, 'I can't do no more.'"
Unfortunately for the troubled 20-year-old, that revelation occurred to her a little too late. On probation and with a mandatory drug test just a week away, it finally dawned on her that her actions could mean jail time -- and even more time away from the son currently in her mother's custody.
"I'm not going to sit here and say it wasn't my fault -- no one forced me to do it," she admitted. "I am really disappointed in myself because, you know, I shouldn't have done it. But then again, it's like so hard not to do it."
Do you think Jenelle will ever turn her life around and regain custody of her son? Share your thoughts on our Facebook page.
