The 45-year-old actress starred as the fashion-forward Lisa Turtle in 86 episodes of the programme from 1989 to 1992.
Reflecting on the snub on "The Dr. Oz Show" on Tuesday, February 18, 2020, Lark, who was primarily on the programme to talk about her bipolar diagnosis, read a passage from one of her journals, sharing, "I have to admit I did feel a bit slighted and hurt when I was not invited to be part of the Saved by the Bell reunion, as well as other cast members events."
"Yet, of course, I also realised that having this puzzling disorder may have played a major part in that factual decision. With that in mind, I am truly thankful for having had the chance to work on a show that has been so successful."
Lark has also been excluded from numerous bonding events her castmates have had since the show ended, such as a dinner last year 2019 to celebrate "30 years of friendship."
And on being left out of such social occasions, the screen star mused, "They have the right to do that and they're happy in their element and they can have it, certainly... (But) family isn't kept complete without its lead."
Dustin Diamond, who played Screech in the teen TV show, is also not expected to be part of the reboot.
The "Saved by the Bell" revival will air on NBC's planned streaming service, Peacock.
