'Teen Mom' Jenelle Evans Busted for Drugs Again

Aug. 10, 2011— -- More trouble for "Teen Mom" Jenelle Evans.

The 19-year-old star of the MTV reality series "Teen Mom 2" was arrested Monday for violating her probation after she tested positive for marijuana and opiate use during a meeting with her parole officer in her hometown Oak Branch, N.C.

According to her attorney Dustin Sullivan, Evans also violated her probation by associating with her on-again, off-again boyfriend Kieffer Delp, "a known drug user," on July 16 and Aug. 6.

"She's facing a 45-day active sentence," Sullivan told ABCNews.com. "The judge could put her in jail for 45 days. Up to this point, I've had 12 or 13 charges dismissed. I've never had to have that conversation with her until now."

Sullivan said he has yet to speak to his client since she was placed behind bars on $10,000 bond Monday. He said she was released that night.

Back in April, the teen mom was sentenced to 12 months probation after she pled guilty to possession of drug paraphernalia.

Evans is due in court August 24.

The reality diva has been on a collision course for some time.

In March, she was charged with simple assault after a video surfaced of her punching a young woman. The woman, Brittany Truett, told ABC News that Evans attacked her in a fit of jealousy because Delp was flirting with Truett.

Sullivan told ABC News in March that his client might be the victim of a set up.

"There are some indicators that Jenelle was set up from the beginning," he said then.

Evans is due in court on the fight case Sept. 9.

"Everything is kind of stacking up right now," he told ABCNews.com Wednesday.

Meanwhile, Delp, 20, has his own troubles. He was arrested the same day as the fight for cocaine possession.

Later, on June 16, Delp was arrested for assault after allegedly punching one of Evan's former friends and her male companion outside an Oak Branch convenience store. TMZ said the young man Delp punched was "bleeding heavily" when police arrived.

Delp is due in court August 31.

Evans, the mother of 2-year-old Jace, found reality fame first on MTV's "Sixteen and Pregnant" and now on "Teen Mom 2." On the most recent season, Evans was shown grappling with signing over custody of her son to her mother.

"She used to be a really sweet girl, outgoing, fun to be around...since she's been on the show, she's got a big head and she's been angry at the world," Truett said.
