Leah Remini made headlines when she left the Church of Scientology and subsequently got in a nasty fight with former pal Kirstie Alley, so naturally we can't WAIT to read her tell-all book!

"It will include my experiences, everything that's taboo to talk about," Leah told Us Weekly at the 15th annual DesignCare event in Malibu last weekend. "It's a time of change. I think the fact that my family has taken a stance and we are on a united front says a lot." We gotta wonder how the church will react, but the King of Queens actress has received plenty of support over the last few weeks from the public and her peers in Hollywood.

Earlier this week, fellow Scientology defector Paul Haggis wrote a letter to The Hollywood Reporter about leaving the church and how Leah was there for him. "[S]he called me as soon as she heard about my letter of resignation," Haggis wrote. "Unlike the rest of my former friends, she expressed real sadness that I was leaving and concern for me and my family ... The fact that she fought within the system so resolutely for so long, never making her feelings public, is a testament to how much she believed in the basic goodness of her friends and the institution. I can't express how much I admire Leah. Her parents, family, and close friends were almost all Scientologists; the stakes for her were so much higher than for me. Her decision to leave was so much braver."
