MTV’s Teen Mom 2 star Jenelle Evans has been arrested yet again, this time for allegedly assaulting her ex-fiance Nathan Griffith’s new girlfriend.

Evans, 23, was charged with assault in the third degree for throwing a glass at Griffith’s 29-year-old girlfriend’s head on Thursday afternoon when she accompanied Griffith to get his belongings from the home he used to share with Evans.

WBTW reports Evans was taken to the Horry County Detention Center in South Carolina after the incident.

This is just the latest development in Evans and Griffith’s break-up saga, which restarted in July when they split up again. In May, she was arrested for a domestic violence incident involving her ex and father of her 1-year-old son, Kaiser, though they got back together after that.

He was arrested in March for the same offense and she was also arrested in 2013 for assaulting him while she was pregnant with Kaiser.

They got engaged in January while on vacation in St. Thomas, which aired on Teen Mom 2 last month.

Evans also has a 5-year-old son, Jace, from a previous relationship.
