Did Sheryl Crow know about Lance Armstrong's drug use? Singer silent over former fiance's doping scandal

In the wake of Lance Armstrong's public admission to taking performance-enhancing drugs, attention is now turning to his former fiancée Sheryl Crow, with questions of what she knew.
Crow, 50, started dating Armstrong in 2003, before getting engaged in 2005 and splitting the following year.
The American singer was with Armstrong, 41, during two of his Tours.
With the second part of Armstrong's interview with Oprah set to air on Friday night, media commentators are speculating as to whether Crow's name will come up.

In September last year Crow told Katie Couric how she found it difficult watching her former fiance stripped of his Tour de France titles.
She said: '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 admired.'
Crow is yet to pass comment on Lance's admissions on national television.
The New York Daily News reported that she was interviewed by federal agents in late 2011, before he was stripped of his titles for using and distributing performance-enhancing drugs the following year.
Meanwhile the Wall Street Journal spoke to two separate sources who claimed Crow knew a lot about the doping scandal.
Armstrong had previously repeatedly denied doping, until publicly confessing in a two-part interview with Oprah, which aired on Thursday night.

He did not appeal the decision of the Court of Arbitration For Sport last year when he was stripped of his Tour de France titles, which he had won for seven consecutive years between 1999 and 2005.
On the day he went public with an admission of doping after years of denials, Olympic officials disclosed one more embarrassment for Lance Armstrong: He was stripped of a bronze medal won at the 2000 Sydney Games.

The International Olympic Committee sent a letter to Armstrong on Wednesday night asking him to return the medal, just as it said it planned to do last month.
The IOC executive board discussed revoking the medal in December, but delayed a decision until cycling's governing body notified Armstrong he had been stripped of his seven Tour de France titles and all results since 1998. He then had 21 days to appeal.

Now that the deadline has expired, the IOC decided to take the medal away.
Part two of Oprah’s interview with Armstrong airs tonight at 9pm.
MailOnline has contacted Crow's manager for comment.
