Looks like things weren't calm for too long -- Ronnie Ortiz-Magro's baby mama, Jen Harley, was arrested again this week. It all stems from a New Year's Eve incident where she allegedly threw an ashtray at... Ronnie.
TMZ reports the arrest was in Vegas early Thursday from a warrant that was issued last month. Jen had actually called the cops on Thursday morning and said someone had a gun, but cops responded to the house only to find out she already had an outstanding warrant.
No word on what the gun situation was about, but the Ronnie had filed a battery report back in January over the NYE incident.
