has added another arrest to her growing rap sheet.

The 23-year-old Teen Mom 2 star was arrested on Thursday in Myrtle Beach, South Carolina, and charged with assault after allegedly hitting her ex-fiancé’s new girlfriend in the head with a glass.

“The victim, a 29-year-old woman, told officers she was at this address, accompanying her boyfriend at his old residence to retrieve some personal belongings,” Horry County police tell ET. “She was assaulted by her boyfriend’s ex, who threw a drinking glass at her head causing injury.”

Evans and Nathan Griffith were engaged in January after two years of dating, but Evans told ET earlier this month that she called things off. The two have one child together, 1-year-old Kaiser.

Meanwhile, Evans’ rep tells ET the incident was a “set up.”

“Nathan provoked Jenelle to make her look bad by bringing his new girlfriend to Jenelle’s house,” her rep claims. “Jenelle is a positive, focused mother. All she wants is the best for her son and to feel safe around her family and friends.”

Evans previously told ET of her split, "I'm enjoying being a mom. I just celebrated my first son's sixth birthday this weekend and it went fantastic. I am not looking to date anyone at the moment. I am focusing on myself."
