lance armstrong & oprah*On Monday, according to a USA Today report, superstar cyclist Lance Armstrong will make his expected doping admission during an interview with Oprah Winfrey.

An anonymous insider says Armstrong will not discuss specific events but will confess that he took illegal drugs to boost his performance throughout his cycling career, despite years of denials and attacks on his accusers.

The interview will be taped Monday and will air on Thursday on the Oprah Winfrey Network. Since the expected admission raises a host of potential legal and financial issues for Armstrong, it might explain why he won’t go into detail.
