The "Franklin & Bash" costars stopped by HuffPost Live on Wednesday to promote their show, but the conversation quickly turned to Diamond.

"This guy's such a d**k," Meyer said. "I don't know Dustin at all, but like, everything I read… [Gosselaar] and I have talked endlessly about Saved by the Bell. I grew up at the same time, I was acting -- I used their sets one time when I did a pilot… the Dustin Diamond thing is just so silly. It's just so negative and it always bums me out."

"It is negative," Gosselaar added. "That I must say. Everything I've heard about his book is it is negative. I don't remember those things. My experience on the show was very positive."

"That's why when people say, 'Oh, you don't like talking about it,' I don't mind talking about it, I just don't really remember that time," the "Saved by the Bell" alum continued. "But also, everything I do remember was extremely positive."

"I think a bunch of it is bulls**t," Meyer continued of Diamond's book "Behind the Bell." "I think he's so full of s**t, like his sex tape… you saw it! That's not him! Screech is not packing that. Get the hell out of here. He doesn't have six Beldings beneath him. There's no f**king way. You're full of s**t, Dustin."

Gosselaar wasn't quite as harsh as the "Clueless" alum, adding, "It's his perspective."
