It's been a year full of ups and downs for Teen Mom's Jenelle Evans and her estranged fiancé Nathan Griffith, and now it seems things have taken another turn for the dramatic.

Earlier today it was reported that police were in the process of tracking down Jenelle after she showed up unannounced at Nathan's apartment and began verbally and physically attacking him.

According to a police report obtained by TMZ, Jenelle called Nathan to inform him that she was outside his home and was damaging his car. 

When police finally arrived, Jenelle had disappeared but Nathan reportedly had "scratches around his neck, a ripped shirt and bruising on the side of his face."

An official statement from Jenelle's PR people via Twitter states that the argument began after Nathan refused to hand over the couple's 11-month-old son Kaiser when the reality star came to pick him up.

This is not the first time in recent months that the couple have been involved in a domestic disturbance. The pair first cut off their engagement back in February when a violent argument broke out between them.

At the time, Jenelle told police that Nathan had pinned her "against a toilet and forcibly removed an engagement ring from her finger" during a disagreement at the couple's former shared home. Nathan, however, claimed that no such incident took place and that Jenelle had removed the ring herself.

Just last weekend, fans began speculating that the couple might be working through their differences, after Jenelle posted an Instagram picture of herself and Nathan hanging out at the Electric Daisy Carnival festival in New York.

Whatever about the picture, it looks ot us like these two could be better off apart…
