London, July 05: During her acceptance speech at the Rock and Roll Hall of Fame induction ceremony Madonna confessed to experimenting with the lethal drug ecstasy. Now a new book by her younger brother is set to spill beans on the singer`s drug addiction.

Christopher Ciccone, one of Madge`s five siblings, who has also worked closely with the singer in the past, has made sensational revelations about her sexual conquests, love affairs, drug-taking and rows with husband Guy Ritchie.

According to the sources, the book `Life With My Sister Madonna` will reveal how the Material girl took drugs with leading showbiz executives.

"The book is a warts-and-all account. Chris was there for all the key moments in Madonna`s life. There is no-one better placed to tell the real story behind Madonna`s public image," The Sun quoted a source, as saying.

However, the singer`s spokeswoman said: "Madonna has not co-operated with any biography about herself."
