Lark Voorhies was reportedly the only “Saved by the Bell” alum to reach out to Dustin Diamond before his tragic death in February 2021.

Diamond’s longtime friend, Dan Block, made the surprising claim during Monday’s upcoming episode of Investigation Discovery’s “Hollywood Demons,” according to Us Weekly.

“[Voorhies] was a really good person, and she left a voicemail for him, and we played it for him before he died. He enjoyed it,” Block shared while filming the upcoming episode.

“She was the only one that really reached out to him and is really heartfelt,” Diamond’s friend added. “I know they had a connection.”

Voorhies reportedly addressed her late “Saved by the Bell” co-star’s death in her own confessional for the “Hollywood Demons” episode.

“That was my very good friend,” the 52-year-old actress shared, per Us Weekly. “I miss him.”

A rep for Voorhies did not immediately respond to Page Six’s request for comment.

“Saved by the Bell” aired on NBC for four seasons from 1989 to 1993.

Besides Diamond as the nerdy Screech and Voorhies as the fashionable Lisa, the teen sitcom starred Mark-Paul Gosselaar as Zack, Tiffani Thiessen as Kelly, Mario Lopez as Slater and Elizabeth Berkley as Jessie.

The show also starred Dennis Haskins as the stern and often befuddled Principal Belding.

Diamond and his fellow “Saved by the Bell” co-stars went on to reprise their roles for the sitcom’s first two spin-offs: “Saved by the Bell: The College Years,” which ran from 1993 to 1994, and “Saved by the Bell: The New Class,” which ran from 1993 to 2000.

But the comedian reportedly suffered a major falling out with his former co-stars over his 2009 memoir, “Behind the Bell,” which alleged drug use, hookups and other scandalous behavior among the teen cast members.

“Everything I’ve heard about his book is it is negative,” Gosselaar said in 2014, adding that he hadn’t spoken to Diamond since 1994. “I don’t remember those things. My experience on the show was very positive.”

Diamond later claimed he used a ghostwriter to write the memoir and apologized for any damage it may have caused.

“I will say, guys, I’m sorry that this has taken advantage of me, the book and other situations,” he said on “The Dr. Oz Show” in 2016. “But I’m sure that you’ve experienced downfalls, as well, in your time, and I’m still loving you guys.”

Meanwhile, Diamond also faced a major legal issue in December 2014 when he stabbed a man in a bar fight in Wisconsin on Christmas Day.

He was ultimately found guilty of carrying a concealed weapon and disorderly conduct and sentenced to four months in jail in June 2015.

Then, in early January 2021, the “Saved by the Bell” alum was diagnosed with an aggressive form of Stage 4 lung cancer called small-cell carcinoma.

Diamond passed away just three weeks later on Feb. 1, 2021. He was 44.

Both Lopez and Thiessen took to social media before their former co-star’s passing to address his tragic lung cancer battle.

“I connected with Dustin earlier this evening and although the news of his diagnosis is heartbreaking, we remain positive that he’ll overcome this,” Lopez, now 52, wrote on Instagram.

“Thinking of you Dustin,” Thiessen, also 52, added in a post of her own.

As for Gosselaar and Voorhies, they later paid tribute to Diamond following the news of his death.

“I’m deeply saddened to hear of the passing of Dustin Diamond, a true comedic genius,” Gosselaar, 52, said. “Looking back at our time working together, I will miss those raw, brilliant sparks that only he was able to produce.”

“Words cannot express the grief that I am feeling right now,” Voorhies added. “Dustin and I had a warm and special friendship, he was a caring gentleman, and my memories of him will always be cherished. I am so very sorry he is gone.”
