Teen Mom star Jenelle Evans is in jail once more after being arrested on Thursday for reportedly throwing a glass at her ex-fiancé's girlfriend.
According to a report from TMZ, Nathan Griffith showed up at Evans' home in South Carolina to collect his belongings, and brought his new female partner along.
An altercation then broke out, at which point the mother of two apparently came out of her home and hurled a glass at the woman, striking her in the head before police were called and the reality star was arrested for assault.
The gossip website goes on to report that Evans' representative said she felt her ex was deliberately provoking her by bringing over his new lover.
This marks the 12th time Jenelle has been arrested since becoming a television star on Teen Mom 2, with most of the charges being related to drugs.
Nathan meanwhile has been arrested in the past for domestic violence, DUI, driving on the wrong side of the road, resisting arrest and driving with a suspended sentence.
The pair have a one-year-old son together but seperated from one another earlier this month.
Jenelle also has another son from her previous marriage who turns six this month, and is currently locked in a custody battle for him with her own mother - who currently cares for him.
Last month saw Evans graduate from high school - something she had hoped to do years ago before being derailed by pregnancy, as documented in the MTV series.
Though she looked to be on the straight and narrow, this will be a huge step back for the young mother.
