"Jill hasn't spoken to any publishers. There hasn't even been a discussion with anybody about a book," a source close to Kelley told the celebrity news website, adding money is not a motive for penning a tell-all.
"Jill's husband [Dr. Scott Kelley] is a very successful surgeon who is very charitable, but definitely not broke," the insider said.
Petraeus, a retired four-star Army general, resigned as CIA director last month when the FBI uncovered his extramarital affair with biographer Paula Broadwell, who sent emails to Kelley warning her to stay away from him.
Kelley has said she reported the emails to the FBI because she felt they were threatening.
