As for what the grudge is about, All About The Tea shared exclusive details about their feud in September of last year. According to the site, it was Resnick's controversial book, Nicole Brown Simpson: The Private Diary Of A Life Interupted, which led to their feud.

In the book, Resnick mentioned Edwards' former husband, Kansas City Chiefs running back Marcus Allen, and accused Allen of having an affair with Nicole after she had separated from O.J. Simpson, who was reportedly one of Allen's close friends. Resnick went on to claim the alleged affair took place during Allen's engagement to Edwards, and continued after the couple wed at the Simpson's home.
