Eric Clapton's ex-wife PATTI BOYD is following the legendary guitarist into writing after signing a lucrative $1.7 million (GBP950,000) book deal for her memoirs. The 1960's style icon married Clapton in 1979 after her relationship with former BEATLE GEORGE HARRISON broke down, and inspired his classic hit LAYLA. Now her amazing life story will be traced with the help of British royal Prince Charles' biographer PENNY JUNIOR, as part of a deal with publishers Hodder Headline. Clapton announced his book deal last autumn (05).
