Mr. Belding -- 'Saved by the Bell' Reunion ... Count Me In!

"Saved by the Bell" is another step closer to a comeback ... Mr. Belding himself -- aka Dennis Haskins -- tells TMZ he's all for a Bayside High reunion, just days after Mark-Paul Gosselaar said he wasn't opposed to the idea.

TMZ broke the story ... Mark-Paul was in L.A. last weekend ... and told our photog, if the upcoming "Boy Meets World" revamp works out, then "maybe we'll do a reunion as well."

That's all it took for Mr. Belding to board the gravy train ... telling TMZ, "I have always supported a reunion of any kind including all of us" ... before adding, "Honestly, the fans still love us and our show so much ... they deserve it!"

As for the rest of the cast, getting them together may be tricky -- Jimmy Fallon nearly made it happen in 2009 ... until Tiffani Thiessen put the kibosh on the whole thing.

But to his credit, Fallon did score the Zack Attack ...
