Harpo Productions said Tuesday that Hunter will appear on The Oprah Winfrey Show on an unspecified date.
GQ magazine last month published the first interview with Hunter in which she addressed the scandal. She told the magazine the affair ended in July 2008 and that the relationship is now something "different." She didn't say whether they are still romantically involved but said Edwards wants to be there for their 2-year-old daughter.
Edwards admitted in January that he is the girl's father after initially denying it. He and his wife, Elizabeth Edwards, are now separated.
