Dustin Diamond, best known as Screech from “Saved by the Bell,” is letting some more lies, err I mean details, slip from his yet-to-be released tell-all book about things that he thinks actually happened but wasn’t around to witness. Diamond claims he could smell a certain kind of smoke coming out of the cracks to his castmates’ dressing room doors. Diamond also says his co-stars frequently hooked up off-camera as well as on it.

Per Us:

“If Kelly [Tiffani Thiessen] was interested in Slater [Mario Lopez] one week, then backstage there was a lot going between them in Mario [Lopez]‘s room,” he tells the new Us Weekly. “Then, if Jessie [Elizabeth Berkley] kisses Zack, then you know Elizabeth Berkley is going in Mark-Paul’s room.”

I highly doubt this is true, but if it were then good for them! I’d follow Zack or Slater to their dressing rooms anyday! What girl in the right mind wouldn’t? His next set of claims take aim at costar Mark-Paul Gosselaar, who played Bayside High hunk Zack Morris, began using steroids before production started on the “Saved by the Bell: The College Years” spinoff.

“He suddenly exploded with manliness, loading 25 pounds of muscle on his once-scrawny frame in, oh, about a month,” says Diamond.

Zack using steroids? I think that claim would be better believed if it were Slater being accused. And scrawny? Come on Dustin, really? Gosselaar, who says the book is nothing but lies and wanted Diamond banned from the Saved By the Bell reunion in August, dismissed his new claims.

“We weren’t in rehab and Mr. Belding wasn’t my crack dealer,” says Gosselaar.

He further alleges that Lark Voorhies, who played Lisa Turtle, all of a sudden “didn’t want to be near men.” Diamond took that to mean she was in an abusive relationship. Remember, he has no idea if this is true though. The name dropping doesn’t stop there! He also felt the need to add that Fred Savage is “a douche nozzle,” Neil Patrick Harris “was an a–hole,” Tori Spelling had “negative [size] boobs,” and Denise Richards was “just another notch on Mario’s bedpost.” Diamond also has come out with other so-called juicy tidbits, including how he says Thiessen, who played Kelly Kapowski, used guys to further her career, how Thiessen struggled with her weight, and how Mario Lopez was a serial womanizer who “hit on every costar.”

So all of this drug use and hooking up Screech alleges, none of it he actually saw with his own actual eyes. What a shocker. Based on these snippets, Diamonds claims are neither scandalous nor interesting. Yawn. I’ll wait the year until the book becomes available at the dollar store to pick up and read for a good laugh.
