She has said publicly that she is planning a tell-all memoir that will, "include my experiences, everything that's taboo to talk about."
As to why she chose to go on a reality TV show just months after leaving the church, Remini said on "DWTS" that she needed the distraction.
"I just think it's going to get me out, you know out of my head," she said. "Out of beating myself up. Out of these bad habits."
The church has said it "could care less" about how the actress does on "DWTS."
"We know this may come as a surprise to someone as self-absorbed as Ms. Remini, but we could care less if she wins or loses on 'Dancing With the Stars,'" a Scientology spokesperson told ABC News in an email after Remini's remarks.
