Behind the Bell: Dustin Diamond Book Cover Unveiled

A decade removed from playing lovable loser Screech Powers on Saturday mornings, Dustin Diamond is writing a tell-all memoir about his days at Bayside High.

The book, titled Behind the Bell, hits shelves September 29. On the cover, a goateed Screech poses above a dated pic of his former Saved by the Bell co-stars.

Diamond was recently shunned from a Saved By the Bell reunion, and cropped out of a cast picture by People magazine, as a result of penning the memoir.

Here's the dirty author on the cover of his text ...

When it was announced in July 2008 that Dustin Diamond, who could certainly use the royalties to pay off his IRS tax lien, would pen a tell-all, Gotham Books was hyping up "sexual escapades among cast members, drug use, and hardcore partying."

But Gotham later dropped the 32-year-old shortly after he turned in his manuscript, possibly due to the gross Dustin Diamond sex tape that featured the shady actor defiling a pair of girls with one particularly nauseating maneuver.

Behind the Bell has since been picked up by a small Montreal-based operation called Transit Publishing. We know at least one guy who will be buying it, too:

"This book is freaking incredible!" Diamond's agent, Jarred Weisfeld, has said. "Everyone that reads it loves it. It is truly one of my favorites of all time."

We doubt Mark-Paul Gosselaar shares that assessment.
