A private funeral Mass will be said this afternoon for actress Farrah Fawcett at the Cathedral of Our Lady of the Angels in downtown Los Angeles.  The “Charlie’s Angels” star died Thursday of a rare cancer at St. John’s Health Center in Santa Monica. A Los Angeles County Superior Court judge issued an ordered that would allow Fawcett’s 24-year-old son, Redmond O’Neal, who has been jailed on a pair of drug-related cases, to attend her funeral. O’Neal will be able to wear civilian clothes and will be accompanied by deputies from the Los Angeles County Sheriff’s Department, said sheriff’s spokesman Steve Whitmore. After the funeral, O’Neal will be returned to Pitchess Detention Center in Castaic, where he is undergoing what the Sheriff’s Department calls an “intense drug rehabilitation program.”
