Ryan, Tatum and Redmond O Neal commemorated the one year anniversary of the death of Farrah Fawcett Friday by visiting the actress Los Angeles gravesite.
Redmond, Fawcett s 25-year-old son, was on a day pass from a sober living facility where he is undergoing court-ordered drug rehab.
“I saw my mom s gravesite for the first time today,” Redmond told PEOPLE at a private gathering Friday evening to celebrate the opening of The Farrah Fawcett Foundation, founded to promote funding for alternative methods of cancer research. “I miss my mother so much. I m glad she s not suffering anymore. I know she s looking down on us.”
“I wish I could talk to her,” Ryan said of his companion of more than 25 years. “Having Farrah gone has been very hard. It hurts. I don t know what Redmond is going through. He is quiet about it, but he must be suffering terribly.”
“Dad is an emotional man, and Farrah s death has taken its toll on him,” says Tatum, who recently reconciled with her father after years of estrangement. “But our being able to reconnect as a family is so beautiful. Farrah would be so happy that we re all here.”
