Shocker: Lance Armstrong may not have told the whole truth during his confessional interview with Oprah Winfrey. Armstrong admitted to doping in the interview, but claimed to have "absolutely" stopped taking any drugs in 2005. According to investigators familiar with the case, Armstrong might have been lying through his teeth about that one. They say Armstrong had an unusually high red blood cell count during the 2009 race, pointing to two possible transfusions. The second half of the OWN interview airs tonight at 9 EST.
