Noted actress Shelley Fabares, who made a significant impact on television since her teenage years on "The Donna Reed Show," has passed away at the age of 82. The news was confirmed by her family in a statement to The Associated Press, with no specific cause mentioned. Born in Santa Monica, California, in 1944, Fabares began acting as a child and made her television debut on "The Loretta Young Show" at the age of 10. Her career spanned decades, with notable roles in productions such as "Our Town," "The Girl Rush," "Never Say Goodbye," and "Girl Happy" alongside Elvis Presley. Fabares's breakout role was as Mary Stone on "The Donna Reed Show," from 1958 to 1963, during which she also had two Top 40 hits including "Johnny Angel." In the late 1970s, she made an impression as Francine Webster on "One Day at a Time" and played James Caan's wife in "Brian's Song." One of her most notable roles was Christine Armstrong on "Coach," although the show took time to find its audience. Fabares married twice, first to producer Lou Adler in 1964, and later to "M*A*S*H" actor Mike Farrell in 1984. She was a dedicated advocate for Alzheimer's awareness, having experienced the disease with her mother. In early 1999, Fabares underwent liver transplant surgery after spending 22 months on a waiting list due to progressive liver failure. Her family remembers her as a "kind," "loyal," "witty," "courageous," and "spiritual" person who will be deeply missed.
