Teen Mom 2: Jenelle Evans' Arrest "Ruined Any Chances for a Season 5," Source Says

Exclusive! A source close to the troubled MTV reality star says she "started heroin in October" and "hasn't been sober"

Teen Mom 2 star Jenelle Evans and husband Courtland Rogers were arrested for alleged heroin possession on Tuesday, and though Jenelle was released on a $10,000 bond later that day, her latest arrest is going to cost her even more.

A source close to the troubled MTV reality star exclusively tells E! News that Evans' latest drug-related trouble has put the future of the popular franchise in jeopardy, saying, "This ruined any chance of a season five."

Jenelle's drama has hindered the series' future for some time now, but the network tried to make a deal with her to insure another season.

MTV said they would start filming the series again only if Jenelle completed therapy and was able stay clean, and our insider says they were close to starting production before Jenelle's latest arrest.

"All she had to do was complete one more week of therapy and [MTV was] going to start filming again," our source reveals.

And though Jenelle tweeted that she's been sober since reuniting with Courtland after he plead guilty to assault and battery, our source says, "She hasn't been sober. That's a lie. She just started the heroin in October."

Teen Mom 2 castmate Kailyn Lowry also weighed in on Jenelle's situation, tweeting, "I'm honestly concerned about her health and safety, so if you have any once of respect, let her breathe and deal with her issues in private."

Jenelle and Courtland, who were both also arrested for alleged simple assault in addition to heroin possession, have been court-ordered to stay away from each other, her attorney Dustin R.T. Sullivan confirms to E! News.

"The order to stay away was from yesterday. She was ordered to stay away from him and he is ordered to stay away as well," Sullivan tells us. "The simple assault alleges she hit him with a piece of furniture."

Evan was also served with a warrant for Evans for child support, but that matters appears to have been resolved.

"There is no longer a warrant out for Jenelle when it comes to child support," Sullivan exclusively tells E! News. "She paid her child support yesterday. It was about $360."
