Ronnie Ortiz-Magro's ex, Jenn Harley, has been charged with a felony following her arrest in Las Vegas earlier this year.
Jenn, who shares 3-year-old Ariana with the "Jersey Shore" star, was formally charged with one felony count of assault with a deadly weapon constituting domestic violence, and one misdemeanor count of battery constituting domestic violence, TMZ reported on Aug. 20.
Jenn, who also appeared on the MTV show when she was dating Ronnie, was arraigned on the charges this week in a Nevada court.
Back in June, Ronnie's ex was arrested in Las Vegas following a domestic incident with her boyfriend, Joseph Ambrosole. Police said the two got into an argument at a gentlemen's club and they were asked to leave (part of the discussion reportedly involved Jenn's drinking.)
The fight allegedly continued during the car ride home and she reportedly threw his phone out the window. When he got out of the car to retrieve it, she took off and left him to fend for himself. Once he got to back to her home via an Uber, Jenn allegedly pointed a gun at Joseph and threatened to kill him.
A month after the incident, Jenn checked herself into a rehab facility in Vegas. Reports claim she recently completed a 28-day stint.
Ronnie, meanwhile, has clearly moved on from his relationship with Jenn. Ironically, he got engaged to girlfriend Saffire Matos the same day as Jenn's arrest.
