Prior to entering rehab, Jenn Harley was running into quite a bit of trouble.
After more details eventually came to light, however, it was reported that Harley was drinking and had an argument with her then-boyfriend Joseph Ambrosole that went too far.
Allegedly, the Jersey Shore star repeatedly hit Ambrosole on the back of his head, pulled a gun on him, used at least one racial slur against him, and threatened to kill him.
Initial reports of her June arrest sparked speculation that her ex Ronnie Ortiz-Magro might have had something to do with the matter, given the inciting incident supposedly occurred at the Las Vegas home the two co-own.
