Sex, Drugs & Steroids Behind The Bell!

Desperate Dustin Diamond (of "Save Screech's House" fame) has found a new way to try to make a quick buck - by alleging that there were some dirty deeds going on on the set of the beloved Saved By The Bell.

Now, some of what he says in his new book (via Us) is kinda like, duh! Kelly and Slater made out? Zack and Jessie smooched off screen? So what?

Sure, mmmaybe we believe there was a little bit o' smoking the weed backstage as Dustin so shockingly reveals, but Zack on steroids?

"He suddenly exploded with manliness, loading 25 pounds of muscle on his once-scrawny frame in, oh, about a month," Screech writes. But could that be true?

"We weren't in rehab and Mr. Belding wasn't my crack dealer,” Mark Paul Gosselaar told the mag.

Hmmm, not exactly a denial, but since Dustin has been known to pull some stunts for attention and cash, we wouldn't put it past him for making this sh*t up! Team Zack!
