Earlier, TMZ reported that the actress was in grave condition at a Connecticut hospital after being on a respirator for over a week, and family members were arriving to say goodbye.
In a statement, her rep said, "Today, beloved icon, Mary Tyler Moore, passed away at the age of 80 in the company of friends and her loving husband of over 33 years, Dr. S. Robert Levine. A groundbreaking actress, producer, and passionate advocate for the Juvenile Diabetes Research Foundation, Mary will be remembered as a fearless visionary who turned the world on with her smile."
Moore has battled Type I diabetes since the age of 33, a diagnosis which led her to be an advocate for diabetes and stem cell research. She also underwent surgery for a benign brain tumor in 2011.
The actress was a television legend, first on "The Dick Van Dyke Show" and then her eponymous sitcom. She also performed on stage and in movies, earning an Academy Award nomination for "Ordinary People."
