Sheryl Crow Speaks Out About Lance Armstrong’s Doping Confession: ‘Honesty Is Always the Best Bet’

Sheryl Crow (Getty Images)It was only a matter of time before Sheryl Crow was going to have to publicly address Lance Armstrong’s doping confession – and that moment came in a new interview with “Entertainment Tonight.”

As one would expect, the 50-year-old didn’t seem all that eager to discuss her controversial ex-fiancé, whom she dated from 2003 to 2006 and didn’t stay in touch with after their split. But the “First Cut Is the Deepest” singer addressed the cyclist’s admission to Oprah Winfrey last week that he cheated to help win a record-setting seven Tour de France titles.

"I think that honesty is always the best bet and that the truth will set you free," Crow said to “ET”in an interview that airs Tuesday. “It must be really hard walk around knowing you are not telling the truth about something. So I always contend that the truth is the best way to go.”

Crow, who was promoting her upcoming gig as a guest mentor on “The Voice,” noted that she watched “bits and pieces” of Armstrong’s interview with Winfrey. She also said, “To carry around a weight like that would be devastating in the long run.”

Crow famously dated Armstrong after he split from his wife, Kristin, and was by his side during his last two Tour wins. While it remains unclear about exactly how much Crow knew about Armstrong’s cheating, she reportedly was interviewed during the federal investigation into Armstrong’s doping activity and shared information she was privy to.

During an interview with Katie Couric in September, after Armstrong was stripped of his titles but before he finally confessed, Crow – who is now a single mom of two adopted sons – said that his fall from grace was difficult to watch.

“I know how hard he worked to win those titles, and you know, it was hard to watch,” Sheryl admitted on “Katie.” “I felt bad. I felt bad for him, I felt bad for his family, and I kinda felt like the rest of America. He is a hero that we watched and looked up to and admire.”
