Late Night host Jimmy Fallon has been the chief proponent of Thiessen reuniting with Mark-Paul Gosselaar and Mario Lopez for a new one-off Saved By The Bell episode, but the actress has now told Parade that it will likely never happen.
"It's not something I want or need to do, and a few of us feel the same way. We're all doing our own thing," Thiessen said, adding: "Jimmy's never called me personally, only his producers. He might be a little harder to turn down."
Thiessen also revealed that she's never read co-star Dustin Diamond's tell-all biography Behind the Bell, which dished dirt on Saved By The Bell's cast.
"My time is very precious these days, and that's not how I want to spend it," she said.
Saved By The Bell ran for five seasons between 1989 and 1992 and even spun off a College Years series.
Thiessen's co-star Elizabeth Berkley said last year that she would be in favour of a Saved By The Bell reunion show.
