In the taped interview, Oprah ask the disgraced 7 time winner of the Tour de France a series of yes or no questions and he comes clean, saying "Yes" to all of her questions when asked if he doped.
Lance had denied the allegations for years -- and when Oprah asked why he came forward now, Lance replied, "I dont know that I have a great answer. I will start now by saying this is too late ... I view this situation as one big lie that I repeated a lot of times ... I am a flawed character."
He added, "I didn't invent the [doping] culture, but I did nothing to stop the culture ... and I am sorry for that."
Lance goes on to say that in his opinion he doesn't think it would be possible to win the Tour de France race 7 times in a row without doping.
It's all rather compelling stuff. The full interview will air Thursday and Friday nights at 9 p.m. EST/PST on OWN.
