“They’re never going to be together,” DeJesus said about Lowry and Marroquin. “They’re so toxic. That’s why I had to remove myself from the situation. It is way too toxic.

DeJesus described the embattled relationship between Marroquin and Lowry. “They would fight and talk and be friends and then fight. It was always back and forth between them .”

DeJesus told Radar that Lowry was to blame for the friction. “ They can only be cool when she’s not in a relationship , when she is, she doesn’t want anything to do with him.”

She said her relationship with Lowry was non-existent. “I don’t hate her. I’m not going to say she’s my best friend, because she’s not. I’m not here to make friends, I’m here to tell my story. I could care less if she’s in my life or not.”

DeJesus offered advice for Lowry and Marroquin. “The should focus on co-parenting before they see if there is a possibility for them to get back together. I pray and hope that they do. The boys like being together. And Kail is the mother of his child and I hope he figures his s**t out.” We pay for juicy info! Do you have a story for RadarOnline.com?
