Actress Kirstie Alley died on December 5 at the age of 71 following a short battle with colon cancer. While she is known for her performances in Cheers and Look Who's Talking, Alley also joined the Church of Scientology back in 1979. Tributes have come in from all who knew Alley and that includes a statement from the Church of Scientology, which looks down on psychiatry and most medical intervention. In particular, she is remembered by the organization for her philanthropic and advocacy work. She has been transparent about her past cocaine addiction and claimed she found strength through the Church. She went on to be a voice encouraging others to do the same.

Fellow Scientologist Lisa Marie Presley owned a waterfront mansion in Clearwater, Florida, that was the spiritual headquarters of the Church; Alley bought this 5,200-square-foot property from Lisa in 2000. In 2007, Alley donated $5 million to the Church of Scientology. Kirstie Alley and addiction Alley battled with drug addiction / © 20th Century Fox Film Corp.

She reached Operating Thetan Level VIII, the highest level. Tony Ortega, the mind behind Scientology blog The Underground Bunker, suggests this impacted her medical care, writing, "Scientologists know that Hubbard was really down on doctors, so they look for alternatives." This raised the question, "Did Kirstie’s training prevent her from seeking medical help sooner, maybe? A lot of people are asking." CHEERS, Kirstie Alley, 'Sisterly Love,' aired April 27, 1989. ©NBC / courtesy Everett Collection Alley would say of the Church of Scientology, "Scientology made me a lot stronger and tougher ... It's made me more honest and more willing to take responsibility for other people." She also found ways to support her acting peers. Cheers co-star Kelsey Grammer says she helped him with his own demons. "I always felt close to her," said Grammer. "She was very supportive of me back in the Cheers days when I was having a bit of an issue with drugs and the law, so to speak. But other than that, I just got a kick out of her."
