Although Snowden was Walters' pick to top her annual roster, she was overruled by network executives because Snowden wouldn't agree to be interviewed for the program, the newspaper said.
ABC recently announced the list would include Snowden, Jennifer Lawrence, Miley Cyrus, Kim Kardashian and Kanye West, Britain's Prince George, the cast of "Duck Dynasty," swimmer Diana Nyad, "Good Morning America" host Robin Roberts and Pope Francis.
The "Most Fascinating Person of the Year" is traditionally revealed on the program.
"We never talk about our bookings ahead of time, but you can rest assured that we will include the most fascinating people of the year," a network representative told the Daily News. "People are fascinating no matter if we interview them or not. The most fascinating decision is not made based on who we interview. You will just have to watch and find out who is No. 1."
