Jamie Lee Curtis, Alec Baldwin, Judy Collins and Lou Gossett Jr. are among a host of entertainers whose struggles with drug and alcohol addiction are detailed in a new tell-all book.

Author Christopher Kennedy Lawford shares celebrity rehab stories in his new book "Moments of Clarity."

In the tome, singer Collins - now sober for 13 years - reveals, "I had been drinking around the clock for four years. My instrument - the voice that had brought me success and saved my sanity - was coming apart."

Remembering the moment before she checked into rehab, she adds: "I brought a jelly jar of vodka and drank it in the airport bathroom."

And actor Lou Gossett Jr. shares his own life-changing experience, which took place during a trip to South Africa.

Gossett reveals, "I was looking out at Robben Island, where Mandela spent 27 years in prison, and I burst into tears because there is absolutely nothing that ever happened in my life to compare to what that man went through and what his people went through. I said, 'What the hell am I doing?' I did worse to myself than any person, white or black, did to me."

The book is set to hit shelves in December.
