Jesse James broke down during an interview in which he publicly admits he cheated on wife Sandra Bullock and says he "took a pretty amazing life and amazing success and marriage ... and threw it away."

Speaking out on camera for the first time since his double life was exposed, James got emotional when Nightline correspondent Vicki Mabrey quoted Bullock's acceptance speech when she told James in front of millions of people, "I never knew what it was like for someone to have my back until I met you." His eyes welled up with tears and he asked to "take a moment" to collect his thoughts.

The full interview with the self-proclaimed "most hated man in the world" airs next Tuesday night on ABC.
