Sheryl Crow and Lance Armstrong dated from 2003 until 2006, before breaking off their engagement. However, during the relationship, Armstrong rode in the Tour de France twice - and won both times. It has since emerged that the disgraced cycling took performance enhancing drugs during both races, catapulting country singer Crow into the spotlight.

Celebuzz.com has learned that the nine-time Grammy winner was named twice in affidavits submitted to the United States Anti-Doping Association, which blew the whistle on the Tour de France winner. According to Armstrong's former teammate Frankie Andreu, the cyclist summoned him to a room in 2004 in a bid to persuade him to convince his wife Betsy to sign a statement retracting her claim that Armstrong told doctors treating him for cancer that he'd taken steroids, human growth hormone, cortisone and EPO. The hospital admission was first reported in a 2004 book co-written by Irish journalist David Walsh titled L.A. Confidentiel, which was only published in in French. In it, Andreu claimed "Lance called me to his room to discuss the situation. He told me that Bill Stapleton (Armstrong's agent) wanted to talk to me about the hospital room and have my wife sign a statement of support for Lance saying the hospital incident did not happen. His girlfriend at the time, Sheryl Crow, was in the room and I felt uncomfortable talking about this in front of her so I did not say much."

It's the first time that Crow, 50, has been directly implicated in Armstrong's doping conspiracy. In an interview to air on Tuesday (January 22, 2013), the country singer tells Entertainment Tonight, "I think that honesty is always the best bet and that the truth will set you free. To carry around a weight like that would be devastating in the long run." She said she caught "bits and pieces" of Armstrong's much-hyped interview with Oprah Winfrey last week.
