They say behind every strong man is an even stronger woman. Unless, that is, she cooperates with investigators.

As you know, Lance Armstrong was stripped of his seven Tour de France titles last week, after he decided to stop fighting to prove that he didn’t take performance enhancing drugs. While he maintains his innocence, many feel that’s an admission of guilt.

But the twist in all of this involves his former fiance, Sheryl Crow. Apparently, Crow was interviewed about Armstrong about his alleged doping. The New York Daily News provides some additional details.

Crow, who was once engaged to the tarnished cyclist, provided information last year in a far-reaching federal investigation into the doping programs that fueled her former fiancé’s victorious Tour de France teams, the Daily News has learned.

Federal agents interviewed the Grammy-winning musician in late 2011, just before a grand jury probe into Armstrong and his associates abruptly ended without any criminal charges being handed up.
