Looks like Jenelle Evans wants to officially clear her name! The infamous Teen Mom 2 star was arrested on April 23 for heroin possession, but she claims she was set up by her husband, Courtland Rogers, and that she's been clean and sober since November 2012.

Jenelle's been attending Narcotics Anonymous classes on the regular, and she recently took a voluntary blood-drawn drug test at LabCorp to prove that she's clean!

"I just did a random drug screen," Jenelle tweeted on May 7 after a fan accused her of being a junkie. "I'm clean."

Unfortunately, Jenelle is unable to explain why she got tested, saying the parties involved in the screening were "top secret."

"Duh... I was ordered to take one for a certain someone and I'm clean bitches," she tweeted.

We're not sure who would ask Jenelle to take a voluntary drug test other than her mother, Barbara Evans (after all, Jenelle is living with Babs), but consider us intrigued!

Why do you think Jenelley was voluntarily tested? Hit the comments and dish your wildest theories!
