There's definitely a bad situation between Ronnie Ortiz-Magro and Jen Harley. The Jersey Shore stars, who are parents to 6-month-old daughter Ariana, have had a tumultuous relationship as of late. As fans well know, Ronnie has expressed some of his troubles with his on-and-off girlfriend on the MTV show, but it was the vicious social media fighting that took place online in April that revealed the two were not on good terms behind the scenes. Following a brief breakup, the two were involved in a domestic dispute in Las Vegas in June, sparked by the sudden death of Jen's dog.
