Farrah's son Redmond O'Neal DID attend the funeral and WAS seen in public! His hair was cut so short he looked quite different than before (presumably a jail requirement that he get a buzz cut).
He served as a pallbearer along with his father, Ryan O'Neal. Many still photographers and TV crews covering the funeral didn't recognize Redmond.
Among the other attendees were Marla Maples, Penny Marshall, comedian Garry Shandling, Robert Greenwald (who directed Farrah in "The Burning Bed"), actor Bruce Davison (who played Senator Kelly in the "X-Men" sequel) and fellow "Charlie's Angels" star Kate Jackson.
We did not spot Angels Jaclyn Smith or Cheryl Ladd.
