Blood streaks are visible on the outside of a vehicle allegedly driven by Jen Harley, the ex-girlfriend of a "Jersey Shore" television show star whom she allegedly dragged with the car during a fight.

Harley was arrested for domestic battery and booked in the Clark County, Nevada Detention Center following the incident Sunday night in which she and Ronnie Ortiz-Magro allegedly fought. TMZ reports there is also blood inside the vehicle on a console, and reports indicate Harley also hit Ortiz-Magro in the face.

The former couple, who have a 1-month old baby named Ariana together (she was inside the car during the alleged fight), was attending a barbecue in Las Vegas prior to the incident in the vehicle, TMZ says. It happened Sunday night.

Harley has since been released from jail.

In recent weeks, Harley appeared on "Jersey Shore Family Vacation," visiting Ortiz-Magro and the other "Jersey Shore" cast members at a home in Miami, Florida, where they were filming. Harley was still pregnant with Ariana when she appeared on the show.
