I read More and am currently reading the Barbara Streisand autobiography which is fantastic (but very different! Though she did have many lovers).
One quick tell-all was "Bad Mormon" by Heather Gay from the Real Housewives of Salt Lake City. It's more about her experience as a Mormon than the show.
"Hidden Valley Road: Inside the Mind of an American Family" is a wild book about a family with many kids, all but two of them (I think) have schizophrenia.
