The pair, who share 2-month-old daughter Ariana, allegedly got into a fight while driving home from a barbecue in Las Vegas, TMZ reported.
Harley was said to have struck Ortiz-Magro in the face during the argument and when he attempted to leave the car, Ortiz-Magro got caught in his seatbelt and was dragged while Harley continued to drive, causing injuries.
Harley was taken to the Clark County Detention Center with the bail set at $3,000, People magazine reported.
Recently, the former couple got into another argument at Planet Hollywood with police being called while Ortiz-Magro was filming Season 2 of MTV's "Jersey Shore Family Vacation."
