Cyclist Lance Armstrong has reportedly admitted to using performance enhancing drugs during a taped interview with Oprah Winfrey.

Armstrong spoke to Oprah at a hotel in his hometown of Austin, Texas.

An article in USA Today cited an anonymous source as saying Armstrong told Oprah he used drugs, although neither Winfrey nor Armstrong's spokespeople confirmed the reports.

The 41 year old was stripped of his seven Tour de France titles last year after failing to deny charges that he doped.

Armstrong's interview will air this Thursday on Oprah's OWN network.
