RoseMarie Terenzio, Hunter's rep, confirms the book will be out June 26.

he loves me," Hunter told the magazine. "I have never had any doubt at all about that. We love each other very much. And that hasn't changed, and I believe that will be till death do us part. The love doesn't go away. It's unconditional."
Edwards went on trial in federal court on charges of illegally using nearly $1 million in unreported campaign contributions to hide Hunter during his 2008 bid for the White House. At the time, Hunter was pregnant and Edwards's wife, Elizabeth, was battling breast cancer, which later took her life.
