‘Jersey Shore’ Star Ronnie Ortiz-Magro’s Baby Mama Jen Harley Arrested For Domestic Battery In Las Vegas ‘Jersey Shore’ stars’ on-again-off-again girlfriend in Las Vegas jail.

Locked up!

Ronnie Ortiz-Magro’s baby mama, Jen Harley, was arrested again, this time for “domestic battery” and is in a Las Vegas jail, RadarOnline.com confirmed.

The Jersey Shore star’s on-again, off-again girlfriend was cuffed on May 16 at 3:05am for “domestic battery,” according to the Las Vegas Metropolitan Police Department Inmate website.

Her bail was set at $3,000 and as of 4:11pm Vegas time she was still in custody.

E! News was the first to report the arrest.

Amid her arrest, Ronnie posted a message on Instagram that read: “You’ll never change your life until you change something you do daily. The secret of your success is found in your daily routine.”

This isn’t Jen’s first time in jail.

Ronnie filed a domestic battery report against her on New Year’s Eve after she allegedly threw an ashtray at him, as Radar previously reported.

“On January 3, 2019, a man came to an LVMPD substation to file a Battery Domestic Violence report against his girlfriend,” according to a statement from the Las Vegas Police Department.

“According to the man, the alleged battery occurred on December 31, 2018 at approximately 11:43 p.m. inside

Jen was also arrested on June 24, 2018 and was charged with domestic battery.

Ronnie checked into rehab after the incident, but Jen seemed to be angry that he stood her up on Valentine’s Day in order to film another TV show.

“Jennifer Harley was arrested for an arrest warrant for Battery Domestic Violence on 5-16-19 during a call for service,” the Las Vegas Metropolitan Police Department PIO told Radar.
