Armstrong won two of his now-invalidated Tour de France titles during his relationship with Crow, which lasted from 2003 to 2006.
Crow's interview with federal agents is believed to have taken place in late 2011, reports the New York Daily News.
Armstrong was last month stripped of his seven Tour de France victories amid an ongoing investigation based on allegations he used banned substances.
