The ex-girlfriend of “Jersey Shore” star Ronnie Ortiz-Magro was arrested after she allegedly dragged him by a car during an argument.

Las Vegas police and her lawyer say that 31-year-old Jennifer Harley is facing a misdemeanor domestic battery charge after a weekend fight.

Harley was arrested Sunday night after officers responded to a report of a man trying to pull a woman from a damaged vehicle near a crossroads southwest of the Las Vegas Strip.

Harley's attorney, Michael Cristalli, confirmed the arrest but said he could not immediately comment about the circumstances.

Police says Ortiz-Magro was bleeding, that officers determined Harley was the aggressor and that the two had a domestic relationship.

Harley and Ortiz-Magro have a young daughter together. TMZ reports that the daughter was in the car at the time of the incident.

Records show Harley was released from jail pending an initial court appearance.
