Diamond to reveal 'Bell' scandals

Dustin Diamond will write a tell-all book detailing the sex and drug habits of the Saved By The Bell cast, New York Magazine reports.

The 31-year-old, who portrayed Sam "Screech" Powers on the popular US high school sitcom, will reportedly expose the antics of his ex-cast mates Elizabeth Berkley, Mario Lopez, Tiffani-Amber Thiessen and Mark-Paul Gosselaar.

The ghost-written book will allegedly feature stories about "sexual escapades among cast members, drug use, and hardcore partying".

Diamond has courted controversy in recent years after selling his own sex tape and announcing his bankruptcy in a live radio interview.
