Elizabeth Edwards is doing everything in her power now to keep her estranged husband's mistress from becoming her children' stepmom, friends reports. Edwards hopes her eldest daughter will become the guardian of her younger children if she succumbs to her late-stage breast cancer, reports the New York Daily News. "She doesn't want Rielle Hunter anywhere near them," says a source. Edward's health has recently "taken a turn for the worse," according to a pal.
She's investigating the legal option of having her 28-year-old daughter, Cate, raise Jack, 10, and Emma, 12, in the event of her death. Cate's a Harvard law grad who's clerking in a federal court in Washington, owns a townhouse and is in a long-term relationship, friends report. John Edwards and Hunter have a 2-year-old daughter, Quinn, but Elizabeth's sister is skeptical the two lovers will ever marry.
