"Jersey Shore" star Ronnie Ortiz-Magro has been ordered to stay away from his girlfriend after allegedly hitting her and kidnapping their 18-month-old daughter, Ariana.

Police in Los Angeles filed an emergency protective order against Ortiz-Magro, 33, following his fight last Friday with Jen Harley.

He was eventually released after posting $100,000 bail. He was arrested early that morning following a physical altercation with Harley.

Under the protective order, Ortiz-Magro must stay 100 yards away from them both for at least one week.

According to police, Ortiz-Magro was uncooperative and officers used a stun gun to take him into custody.

Harley has faced misdemeanor domestic battery cases three times in Las Vegas relating to scuffles with Ortiz-Magro, including one this year and cases in 2016 and 2018. All were dismissed.
