Tom Cruise’s connection to Scientology is far from a secret. In fact, it’s probably the first thing moviegoers today associate him with, perhaps even above Katie Holmes or the Mission: Impossible franchise.

Kirstie Alley doesn't care what the Scientology haters have to say because she claims the controversial religion saved her life.

The world's hottest 61-year-old admits she thought the religion was a scam like 99 percent of the population until it helped her kick a cocaine addiction she claimed was life threatening. She said that after reading a book by Scientology founder L.
