Additional names for the roster will be disclosed shortly, the television network said. The year's No. 1 most fascinating person will be revealed on a 2-hour ABC News special, which is to air Dec. 14.
"I was absolutely delighted when ABC approached me to do another year of 10 Most Fascinating People," Walters said in a statement. "I know we said last year was our last, but there are just too many fascinating people out there... and you never pass up the opportunity to interview Oprah, Neil, Chelsea or Scarlett."
Walters, 85, retired from co-hosting the daytime talk show The View earlier this year.
