Lance Armstrong, who was recently stripped of his seven Tour De France titles, was in the prime of his cycling career when he met and eventually became engaged to Grammy winning singer Sheryl Crow.

The couple dated from 2003-2006, calling off their engagement two weeks prior to announcing she had breast cancer.

Many wonder, with the drug allegations against her ex-fiance, what does Sheryl Crow know?

Aside from the many people who cooperated with the U.S. Anti Doping Agency's investigation, ex-fiance Sheryl Crow was reportedly one of those people.

Crow was reportedly with Armstrong in Europe while he was cycling, and in locations where the alleged doping took place!

In late 2011, Sheryl Crow gave information to federal investigators when meeting with them.

What information did she give the authorities? Crow's attorney throughout the investigation, Jay Cooper told the New York Daily News, "no comment."

Well after getting stripped of his seven titles, Crow's ex still claims his innocence!
