It's no secret that Jenelle Evans is on a downward spiral.

A rep for the Brunswick County Sheriff's Office tells TMZ the Teen Mom 2 star was arrested Monday in North Carolina for violating a domestic violence protective order. The 20-year-old single mother was immediately taken into custody.

Details surrounding Evans' recent arrest are unclear, though she was arrested six days earlier for allegedly harassing her ex-roommate, Hannah Inman.

On Sunday, Evans attended church with boyfriend Gary Head before going to "shoot guns for the first time with him," according to her official Facebook page.

Evans -- mom to son Jace, 2 -- is still on probation for her involvement in a 2011 street fight.
