Is 'Teen Mom 2' Star Leah Calvert Addicted To Prescription Pills?

Following In Touch Weekly's report regarding Calvert's alleged use of Vicodin, Lortab, Percocet and oxycodone, a source, reportedly close to the Teen Mom 2 star has come forward, claiming Calvert's drug use has been going on since 2009.

“She was snorting Loratabs in ’09 and messing with Oxy,” a source told The Ashley during an Oct. 22 interview. “She was doing two to six pills a day if not more in 2012. It’s only gotten worse. She has a Percocet problem that she covers up with a prescription. But just because she’s prescribed 30-60 pills a month by a doctor doesn’t make it OK to do hundreds.”

Just this month, Calvert has been faced with several shocking rumors. The most substantial, of course, would be the allegations made by her husband, Jeremy, who recently claimed he caught her cheating on him with her ex-boyfriend Robbie Kidd. Jeremy told his Twitter fans of the infidelity, and revealed his plan to divorce Calvert.

Days after Jeremy's announcement, Calvert's supposed drug dealer spoke out, revealing shocking details about her alleged drug use.

"I used to give Leah the pills myself; she’s picked up 30 to 40 pills at a time from me,” the alleged drug dealer told In Touch. “She was withdrawing $1,000 a week to buy pills."
