"Behind The Bell": Dustin Diamond, Screech, Spills Secrets From "Saved By The Bell" (VIDEO)

Dustin Diamond, better known as Screech from the hit show "Saved by the Bell," has a new book out, "Behind the Bell," in which he spills secrets about the show and his co-stars. One piece of gossip he reveals, or claims, is that his Mark-Paul Gosselaar (Zach Morris) used steroids.

Gosselaar has denied this, but Diamond insists it's true:

Well he admitted it to me when we were sitting in a limo. He told me straight out, face to face, so it's kind of hard to refute that. Plus, you can't lie to your eyes. If you watch the college years you can see massive amount, 25 pounds of growth occur in about two months.

Diamond also claims that drug use occurred and that Mario Lopez (Slater) was a ladies man from a very young age. We await a denial from Lopez.
