Sheryl Crow was engaged to Lance Armstrong for five months in the mid-2000s when the cyclist still held a record-breaking seven consecutive Tour de Frances titles—i.e., back when he was famous instead of infamous.

And even though they parted ways in February of 2006, it seems Crow wasn't able to escape the storm of scrutiny that surrounded Armstrong after allegations surfaced that the world's most famous cyclist had been doping during his championship title-winning run.

According to the New York Daily News, Federal prosecutors interviewed Crow in late 2011 about Armstrong as part of a two-year investigation into whether her fiance had used performance-enhancing drugs. Crow had been in a relationship with Armstrong since 2003 and was with him for his final two Tour de France victories.

Although the Feds closed the inquiry without filing any criminal charges in February, just four months later the U.S. Anti-Doping Agency formally charged Armstrong with doping. After the once-celebrated athlete refused to fight the charges against him, he was stripped of his seven Tour de France titles.

The Daily News also reported that during the celebrity couple's relationship, Crow was staying with Armstrong in a Spanish apartment that two of his former teammates allege was a doping distribution point for Armstrong to fellow teammates.

But what Crow knew—and what she told federal investigators last year—remains a mystery. Unsurprisingly, neither Armstrong nor Crow gave Daily News comments on the report.
