Meanwhile in Florida . . .

Some guy had apparently been partaking in copious amounts of adult beverages when he strolled into a wedding reception at the Grand Plaza Hotel in St. Petersburg earlier this week.

Was he a friend of the bride or the groom?  Neither!

Dude totally crashed the wedding, and not all cool like the movie “Wedding Crashers,” where one of the rules is to only draw attention to yourself if it’s in a positive way.

The crasher’s name is Mark Saunderson (37), and he brought on the wrong kind of attention when stumbled onto the dance floor . . . during the newlywed’s FIRST DANCE!

Security showed up, and that’s when Mark took off, leading the pursuit all the way up to the roof where he was caught and held until police arrived.

The wedding crasher was charged with disorderly conduct, but the newlyweds weren’t even upset about it. They thought it was comical and hoped Mark had fun for the short amount of time he was there.
