Dennis Haskins' 'Heartbroken' Saved By The Bell Co-Stars React To The Death Of TV's Mr. Belding

Dennis Haskins, the actor best known for portraying Principal Richard Belding on "Saved by the Bell," died on Sunday, and his former co-stars from the iconic teen sitcom are paying their respects online.

"Heartbroken to hear about my old friend Dennis Haskins," Mario Lopez, who played macho meathead A.C. Slater, writes on Instagram. "He played the principal, but Dennis was the biggest kid on the SBTB set. If you knew him, you loved him—and if there was karaoke, you knew Dennis was getting on that mic! I'm grateful for the laughs, the memories, and the friendship we shared all these years. Rest easy, my friend. You'll always be part of our Bayside family."

Lark Voorhies, who played fashionista Lisa Turtle, echoes Lopez's sentiments in an Instagram post of her own: "Knowing Dennis Haskins for almost 40 years has been one of the truest blessings of my life, which makes losing him hurt so deeply," she writes. "We shared so much history together from our earliest days, and through it all, he remained a fabulous person, a loyal friend, and someone with such a kind, gentle heart. I am truly heartbroken by his passing and will miss his warmth and laughter more than words can say. Rest in peace Dennis, you will always hold a special place in my heart."

Tiffani Thiessen, who played spunky cheerleader Kelly Kapowski, writes on Instagram, "Dennis Haskins was a steady presence in my teenage years, the kind of figure who kept us in line while making sure we knew he was in our corner. I will always remember his kindness and be grateful for the memories we as a cast got to share with him. RIP Mr. B."

Haskins starred in all four seasons of "Saved by the Bell" (1989–1992), as well as its short-lived predecessor "Good Morning, Miss Bliss" (1989). He reprised his role in the made-for-TV movies "Saved by the Bell: Hawaiian Style" (1992) and "Saved by the Bell: Wedding in Las Vegas" (1994), and guest-starred in an episode of "Saved by the Bell: The College Years" (1993). He then returned to Bayside High School as a series regular for all seven seasons of "Saved by the Bell: The New Class" (1993–2000).
