Grammy Award-winning musician Sheryl Crow watched disgraced cyclist Lance Armstrong receive a blood transfusion in 2005 and later told federal investigators, according to a book that is set to be released next week.
The New York Daily News reports that Crow, who was dating Armstrong at the time, spoke with a Food and Drug Administration criminal investigator and that he gave her a proffer agreement, which is document that protects witnesses from criminal prosecution if they cooperate with an investigation.
The book,"Wheelmen: Lance Armstrong, the Tour de France, and the Greatest Sports Conspiracy Ever," written by Wall Street Journal reporters Reed Albergotti and Vanessa O'Connell, details Armstrong's systematic doping with his teammates that propelled Armstrong to seven straight Tour de France wins. He was later stripped of those titles and banned from the sport for life.
"Rather than try to hide the transfusion from her, Armstrong was completely open about it," according to excerpts from the book. "He trusted that Crow would have no desire to tell the press or anyone else about the team's doping program. He explained that it was simply part of the sport - that all cyclists were doing the same thing."
Armstrong admitted to doping in a television interview with Oprah Winfrey in January.
