Less than 24 hours after she told a fan on Twitter Monday that she was "doing great...and I'm sober!" "Teen Mom 2" star Jenelle Evans was arrested in Brunswick County, N.C., and charged with possession of heroin, simple possession of a Schedule II controlled substance and possession of drug paraphernalia.
The troubled MTV star's lawyer, Dustin Sullivan, tells TODAY.com that Evans also was charged with simple assault, and failure to pay her child support payment to her mother, Barbara Evans.
Evans' husband, Courtland Rogers, was also arrested Tuesday, and has been charged with possession of heroin, as well as assault on a female.
"Courtland is currently on probation for the assault on a female charge that Jenelle filed against him in January," Sullivan said. "He recently pleaded guilty to that charge and was on probation for it when he was arrested today."
Sullivan said that Evans' charges were split up and that she received two separate court dates: one in May for the misdemeanor charges, and one in June to deal with the felony drug charges.
"She was very upset when I saw her in court," Sullivan tells TODAY.com. "She was crying in court and she denies having any involvement with the drugs that were found."
Evans, who has made two trips to rehab in the past two years, was shown on Monday night's episode of "Teen Mom 2" discussing her drug use, and took to her Twitter account Monday night to defend herself.
Sullivan said that while Evans has been bonded out of jail, Rogers was still behind bars when Evans left jail. Coincidentally, Evans' former fiance, Gary Head, turned himself into the Brunswick County Jail today to begin serving a sentence for a DWI charge.
"At one point today, Gary, Jenelle and Courtland were all in the jail behind bars at the same time," Sullivan said.
According to Sullivan, Evans wasn't on probation at the time of her arrest, but is currently prohibited from having any contact with Rogers.
