Whitney Houston`s friend writes book

London: Late singer Whitney Houston`s close friend and gospel singer BeBe Winans, who performed at the singer`s funeral, has written a book titled ‘The Whitney I Knew’.

Releasing July 31, the book will include never-seen photographs of the pop superstar.

Winans promises to reveal heart-breaking accounts that led to Houston`s ultimate defeat, reports a website.

Houston was found dead in the bath of her Beverly Hills hotel room in February.

Not only Winans, Houston`s mother Cissy will also release a book about her daughter in February next year.
