She has made repeated visits to rehab to beat her drug abuse problems.
And now shocking footage has emerged of a woman, believed to be Teen Mom personality Janelle Evans, snorting a crushed up painkiller.
The 21-year-old recovering heroin addict is spotted bending over a counter and inhaling a white substance said to be a crushed up Percocet tablet in the video, which was shot in summer last year.
A source told Radar: 'Jenelle was on probation at the time and she bought pills from a drug dealer and crushed them up.
'She could be really violent when she didn’t get her way and throw temper tantrums.
'But when she snorted the drugs she was really mellow and zoned out.'
Dressed in a T-shirt and jeans, she keeps her hair out of the way by wearing it in a bun as she inhales her drugs.
The source claims she used Percocet instead of a harder drug as she knew any traces would be out of her system in just 72 hours, which would help her avoid being caught out by any probation ordered drug tests.
In 2009 a Federal Drugs Agency advisory panel recommended that Percocet, Vicodin, and every other combination of acetaminophen with narcotic analgesics be limited in their sales.
This was because of their contributions to an alleged 400 acetaminophen related deaths in the United States each year, that were attributed to acetaminophen overdose and associated liver damage.
Meanwhile, a friend close of the MTV star says Evans is aware of the existence of the video, and thinks it is 'stupid.'
They added: 'The video was taken a long time ago, before Jenelle went to rehab and stopped doing drugs.
'She said it was stupid. She was obviously not doing great when that was shot and it was mean of someone to take that video of her.
'But now she’s better and isn’t doing drugs anymore.'
It is just the latest in a long line of drug controversies to dog the MTV personality.
Earlier this month her husband Courtland Rogers claimed she was using the heroin before she had a miscarriage in January.
He made the claims after being released on bail following a complaint she made to police he assaulted her.
Since first appearing on MTV, Evans has been arrested seven times on charges including breaking and entering, assault, violation of probation, and possession of drugs.
She also publicly feuded with her family and other cast members and has previously been forced to give up custody of her son Jace.
Her mother, Barbara Evans, was tasked with raising the three-year-old while she received treatment in rehab.
