Dustin Diamond has once again publicly apologized to his former "Saved by the Bell" cast mates for his shocking behavior over the past decade.

Now 39-years-old, the actor famous for playing Screech Powers looked down the barrel of the camera during an appearance on "The Dr. Oz Show" and delivered a heartfelt message.

“I will say, guys, I think you’re fantastic, working with you has been just one of the icons of my life and I’m sorry that this has taken advantage of me,” he said.

“But I’m sure that you’ve experienced downfalls, as well, in your time and I’m still loving you guys.”

Diamond’s relationships with his former co-stars Mark-Paul Gosselaar, Mario Lopez, Lark Voorhies, Tiffani Thiessen and Elizabeth Berkley soured in 2009 when he released a tell-all book called "Behind the Bell."

In the memoir, Diamond claimed that Tiffani Thiessen was hooking up with both Mario Lopez and Mark-Paul Gosselaar at the same time.

He also claimed that some of the young stars would smoke marijuana in their dressing rooms.

But Diamond’s most damaging claim was that Mario Lopez had sex with a fan "against her will" and that NBC lawyers paid the girl "somewhere around $50,000" to stay quiet.

Understandably, Diamond’s former "Saved by the Bell" co-stars weren’t thrilled by the claims.

Mark-Paul Gosselaar said, "Everything I've heard about his book is that it is negative, and I don’t remember those things because my experience on the show was very positive."

Diamond came face-to-face with another former co-star, Mario Lopez, on an episode of Extra in May this year.

"The book didn’t exactly paint a flattering picture of your fellow castmates," Lopez said to Diamond.

But the troubled star, who spent three months in prison earlier this year after being found guilty of carrying a concealed weapon and disorderly conduct for a bar fight in 2014, blamed the book’s bogus claims on his ghostwriter.

"I wanted to write a book about my life," Diamond explained to Lopez.

"I was supposed to talk to a ghostwriter for 40 hours total. I talked to a guy for 90 minutes total ... another two weeks go by, and I get something in the mail, I get a copy of the book ... They fabricated a whole bunch of stuff ... I [was] kind of super railroaded on that."

Diamond told Lopez that he’s well aware of the damage he caused with the book.

“I haven’t talked to Marc Paul or Elizabeth or Tiffani in ages, so I can’t imagine what they think,” he said.

It sounds like Diamond hasn’t made much progress with his former co-stars since that May interview with Lopez.

“It’s doing interviews like this and getting the word out there,” Diamond said to Dr. Oz this week about how he’s attempting to say sorry.

“This is my best weapon for repairing the damage that was caused by things that were done by people who took advantage of me and the situation I was in at the time.”
