Ryan O'Neal Last February, the 66-year old "Love Story" star was arrested on suspicion of assault with a deadly weapon for discharging a gun during a fight with his 42-year-old son, Griffin. Charges were later dropped after prosecutors determined there was insufficient evidence, and O'Neal told this newspaper that he fired the weapon in an attempt to scare off his son who was swinging a fireplace poker at him. Griffin's sister, Tatum, later weighed in on "Entertainment Tonight," "No matter what my dad is saying in the press, Griffin was not trying to start a fight with him. He was attempting to protect Redmond [Ryan's son with actress Farrah Fawcett]." This was the second publicized altercation between father and son -- in 1984, Griffin O'Neal told People magazine how his own drug-addled behavior had provoked Ryan O'Neal to slug him in the mouth, knocking out two front teeth. In her book, "A Paper Life," Oscar-winner Tatum O'Neal also alleged physical and emotional abuse by her dad. Ryan O'Neal has denied his daughter's claims. (Tatum O'Neal also had her own battle with drugs, and in 1998, her 7-year-old daughter found a syringe in the apartment. Afterward, Tatum O'Neal lost custody of her kids to her ex-husband John McEnroe.) Pictured: Ryan and Tatum in 1973 film "Paper Moon."
