'Teen Mom' Jenelle Evans Arrested AGAIN ... for Stalking

Call her DMX ... because "Teen Mom" star Jenelle Evans' mug shot collection nearly rivals the rapper's -- after the 20-year-old was arrested AGAIN today in North Carolina ... for stalking.

A rep for the Brunswick County Sheriff's Office claims Evans was arrested as a result of an outstanding warrant against her for cyberstalking. We're told Evans turned herself in to authorities after learning about the warrant.

It's unclear who Jenelle was allegedly harassing on the Internet -- but sources tell TMZ, the charge stems from an ongoing feud between Jenelle and her old roommate, who has previously accused Jenelle of harassment.

Jenelle was booked on misdemeanor stalking in Bolivia, NC. She has since been released on $1,000 bond.

Calls to Jenelle's camp were not immediately returned.
