Who topped the list this year?
Tonight, Barbara Walters crowned General David Petraeus as her Most Fascinating person of 2012.
"David Petraeus was not chosen this year for his war record or his exemplary service to his country," said Walters. "This is about military honor, colliding with sex and lies in the digital age."
The former head of the CIA stepped down in November after an extramarital affair was discovered with his biographer Paula Broadwell. Petraeus, 60, was also given the number one spot in 2010.
Additionally, the legendary journalist sat down with Argo actor/director Ben Affleck, British-Irish boy band One Direction, Olympic gymnast Gabrielle Douglas, Family Guy creator Seth MacFarlane, 50 Shades of Grey author E.L. James, Secretary of State Hillary Rodham Clinton and New Jersey Gov. Chris Christie. Prince Harry and Honey Boo Boo were also featured on the list, but were not interviewed.
This is Walters' 20th season highlighting some of the year's biggest names in entertainment, sports and popular culture.
