Fist pumping just took on a whole new meaning. Ronnie Ortiz-Magro might think twice before cheating on his girlfriend again — Jen Harley was reportedly arrested for beating up her ex-husband and threatening him with a baseball bat before dating the Jersey Shore star.

In the 2013 police report obtained by Radar Online, her former partner Joshua Rogers claimed the domestic violence started when Jen came home and "was upset that he was drinking with her roommate." He went on to detail how the brunette beauty hit him in his face with her fist and continued "swinging erractically." She then proceeded to pick up the bat. According to an officer on the scene, "Rogers had dried blood on his bottom lip along with blood on his bottom teeth."

However, in Jen's defense, she told officials that she was acting in self-defense after her ex allegedly put her in a headlock and she only grabbed the bat to "scare" him. At the time of the incident, the couple was already divorced but dating again. The case was ultimately dismissed.

Ronnie, 32, and Jen, 31, who began dating in 2017, welcomed daughter Arianna together earlier this month. Ronnie is currently appearing on the MTV series Jersey Shore Family Vacation, and was caught cheating on his baby mama, who was pregnant at the time, on camera while filming in Miami. Along with the infidelity, Ron can't seem to stop talking about his ex-girlfriend Sammi "Sweetheart" Giancola — and his co-stars are beginning to notice.

"Ron needs to stop talking about Sam and like move the f–k on," Deena Cortese said on the show. "Sam told me that he used to call her on blocked numbers and used to be like really weird. She was afraid she was going to get in the house and he would get drunk and spiral and try to get back with her or something." Ron denied he still has feeling for Sammi, adding, "I have a kid on the way, you think I give a f–k what she does?" Right… Let's just hope Jen is not watching.
