“Ronnie Ortiz-Magro is currently the subject of domestic violence restraining orders banning him from disturbing the peace of my client, Jenn [sic] Harley,” Bloom prefaced the statement.

“Nevertheless he chose today to post cruel and false statements about her, along with her work phone number, causing her to be subjected to a barrage of hate calls and texts from his followers. Jenn Harley simply wants to work and care for her baby daughter in peace.”

“We will be taking appropriate legal action,” the statement concluded.

“All I have ever done is provide for my family and try to give a life to them I never had… I didn’t even want to stoop to this pathetic level of instability,” he continued.

“But how many fake articles can one person wake up to? How many fake lies can one person deal with that my daughter will have to hear? How much emotional abuse, mental control can one person tolerate? How many people can I let this person try to destroy in my life that I carry about? I’m sticking up for myself, my daughter and the people in my life that this mentally unstable person has been harassing & threatening!!”
