“Saved by the Bell” star Dustin Diamond, aka Screech, wrote a tell-all book about his sitcom cast mates.

The book titled Behind The Bell details what went on behind-the-scenes on the popular 1990s sitcom. 

In the book, Diamond alleges there were backstage hook-ups among the cast members and drug use.

He also alleges Mark Paul Gosselaar, (known as Zach Morris) used steroids to make himself buff during “Saved by the Bell: The College Years.”

If you want to know the specifics, you’ll have to wait until the book hits shelves Sept. 29.
