O.J. Simpson has reportedly admitted to the murder of Nicole Brown Simpson in 1994.

Simpson confessed to a producer for Oprah Winfrey, and he will reportedly repeat the confession to Winfrey during a televised interview. Several news outlets are citing the National Enquirer with breaking the news.

The initial interview took place in prison, where Simpson is serving a nine-year sentence for kidnapping and robbery.

Simpson claimed he stabbed Nicole in self-defense.

The former NFL running back and part-time movie star was acquitted after being charged for the murders of his ex-wife and Ron Goldman.

Update: Winfrey's representative has denied the report.
