It has been confirmed by the Associated Press:
In an interview taped tonight with Oprah Winfrey, Lance Armstrong admitted to using performance-enhancing drugs during his days as a professional cyclist.
The rumor of such an admission has been circling for days, with Armstrong apologizing over the weekend to members of his Livestrong foundation.
It remains unclear exactly what Armstrong told Winfrey - the interview airs on OWN Thursday night - which will be important in terms of the lawsuits that have already been filed against Armstrong.
The former world champion was stripped of all seven Tour de France titles last year after the U.S. Anti-Doping Agency released a 1,000-page report that painted him as a drug user and drug pusher, someone who manipulated the system and pressured fellow riders to follow his methods.
Led by Armstrong, the U.S. Postal Service team carried out "the most sophisticated, professionalized and successful doping program that sport has ever seen," according to Travis Tygart of the USADA.
Through years of allegations, Armstrong both denied any kind of drug use and reacted combatively against those who leveled the charge against him.
Why come clean now? He supposedly wants to be free to compete in sanctioned marathons and triathlons.
Teased Oprah in a Tweet not long after chatting with the disgraced athlete: "Just wrapped with @lancearmstrong More than 2½ hours. He came READY!"
