At 10 years old, Tatum O'Neal won an Oscar for her role starring in "Paper Moon" opposite her father, Ryan O'Neal. While they had undeniable on-screen chemistry, off-camera tension was building. When she was 15, Tatum's dad moved out -- and in with Farah Fawcett -- leaving Tatum and her younger brother to take care of themselves. Tatum and Ryan didn't speak for 20 years, and they began repairing the relationship only in 2009 after Fawcett died from cancer. Although the father-daughter pair co-starred in the OWN series "Ryan & Tatum: The O'Neals" -- attempting to reconcile through counseling and discussion -- the relationship remains strained.
