'Jersey Shore' Star Jen Harley Allegedly Pulled A GUN On Boyfriend During Heated Argument

Jen Harley allegedly pulled a gun on her current boyfriend, Joseph Ambrosole, during a heated argument that eventually landed the reality star behind bars.

According to multiple reports, the 'Jersey Shore' star and her BF were arguing about where to park and how much alcohol was being consumed as the couple pulled up to the 'Crazy Horse' strip club in Las Vegas. At that point, the couple's argument spilled into the bar, and it got bad enough, that security asked them to leave.

As we reported Jen Harley was arrested over the weekend on charges of domestic violence and assault with a deadly weapon.

Turns out, according to reports, the argument didn't end inside of the Vegas hotspot. Apparently, the couple continued the argument on the ride home, and at some point, Jen started pounding her BF on the back of the head, and eventually threw his cell phone out of the car window. Of course, Joseph reportedly had to pull over and search for the missing phone, and once he was out of the car, Jenn allegedly took off -- leaving him on a street corner where he was forced to get another ride home.

To make matters worse, the argument intensified after the couple got home, and Jen allegedly pulled A GUN on her boyfriend. According to law enforcement, the reality star said something along the lines of "I'll shoot and kill you," and eventually left the scene.

As you know, eventually police were able to track Harley down and arrested her on charges of domestic violence and assault with a deadly weapon.

The good news, our sources say Ronnie Ortiz-Margo was already scheduled to have his daughter (the one they share together) for fathers day weekend and she is now safe and sound with her father. We're told Ronnie will retain custody of the child until the situation is cleared up with his ex and it is safe for her return. It's unclear if Oritz will file for full custody, or just help while the legal situation is worked out in Las Vegas. As you know, Jen and Ronnie had their own issues with violence in their relationship.

As we reported, Ronnie shared photos and video of himself on Sunday enjoying father's day with his 3-year-old daughter at Disneyland. The youngster, Ariana, looked pumped to be visiting the Happiest Place on Earth especially while her mother was dealing with the drama in Las Vegas. “Disneyland with my Princess,” Ronnie captioned a photo on Instagram where he is giving Ariana a kiss while she sits in a stroller.

Jen Harley is currently out on a $5,000 bond and is due back in court at some point in the future.
