"Chase and I are no longer engaged.""After experiencing a lot of ups and downs and still living apart, Chase reconnected with a woman with whom he has had a long history. Chase recently told me this information and the fact that it had resulted in a pregnancy. Chase will be a father in October," Whitney continued. "I’m not interested in anything hateful being directed toward anyone. I would ask for privacy for all involved as we move on and focus on the future."Despite initially trying to keep his baby mama's identity private, fans found out.Meanwhile, Chase posted about their split on his own Instagram — while also making it crystal clear that he will not be divulging details about the woman with whom he's expecting a baby. \n\n"I don't even know where/how to start.
