Veteran singer/songwriter Rita Coolidge has put her ex-husband Kris Kristofferson and former lovers Graham Nash, Stephen Stills and Leon Russell on high alert by revealing she'll open up about her famous affairs in an upcoming memoir.

The We're All Alone star, 69, has landed a deal with Harper Collins to publish her autobiography, which will detail her small town upbringing in Lafayette, Tennessee and her rise to fame in the late 1960s.

Coolidge has also promised to reveal all about her romantic life and the love triangle she became caught up in after leaving rocker Stills for his bandmate Graham Nash, which has long been considered a contributing factor for the break up of their supergroup Crosby, Stills, Nash & Young in 1970.

She went on to marry Kristofferson, who she divorced in 1980 after a seven-year union, and enjoyed a relationship with Russell, who was inspired to write the song Delta Lady for her, and a close friendship with British rocker Joe Cocker.

The book, also titled Delta Lady and co-written by Michael Walker, is expected to hit retailers next year (15).
