Finley was also once accused of using high-heeled shoes to pummel her former husband, former Angels pitcher Chuck Finley, The Los Angeles Times reported Wednesday.
A statement from the Orange County district attorney's office said that the cocaine was found May 21 in the San Juan Capistrano apartment that Finley lives in with her two children. Finley faces up to three years in prison if convicted on the possession charge.
It has not been released why the police were at Finley's apartment or why there was a delay in filing the charges, the Times said.
Finley's arraignment is scheduled for Dec. 18 at Harbor Justice Center in Laguna Niguel.
