Janet Jackson and Jermaine Dupri are not back together. JJ went on a radio station in Atlanta yesterday and referred to JD as her 'ex' saying, "I'm not the type of girl that stays in touch with an ex like that. [But] Jermaine is one of my best friends. I love him to death. We're still connected. We're still good friends. We still talk... We're there for one another. I think it will remain that way for the rest of my life."
