Ronnie Ortiz-Magro's ex Jenn Harley is making changes in her life in the wake of her recent domestic violence arrest.
"Jenn Harley has decided to check into a Las Vegas rehab facility to seek treatment for her alcohol dependency," a rep told TMZ. "She made the decision to get help because she wants to be the best parent she can be for her children."

Jenn, who shares 3-year-old daughter Ariana with the "Jersey Shore" star, began the 28-day program on July 17. Her rep maintains that it was Jenn's idea to get help.
Last month, Jenn was arrested in Las Vegas following a domestic incident with her boyfriend, Joseph Ambrosole. Police said the two got into an argument at a gentlemen's club and they were asked to leave (part of the discussion reportedly involved Jenn's drinking.) The fight allegedly continued during the car ride home and she reportedly threw his phone out the window. When he got out of the car to retrieve it, she took off and left him to fend for himself. Once he got to back to her home via an Uber, Jenn allegedly pointed a gun at Joseph and threatened to kill him.
Jenn soon fled the scene, but cops eventually tracked her down and arrested her for domestic violence and assault with a deadly weapon.
The couple split afterward.
