A smokin' hot model with a massive following was arrested during the Super Bowl on Sunday after she hopped over some railing, tried to go running on the field and then flashed her ass.
You can see in video of the alleged incident ... Kelly Green -- aka Kelly Kay -- was tackled by security before she could really make a scene during the Chiefs-49ers game.
But, she still managed to show the crowd her butt while cops were taking her away ... and you can see in the footage, fans were loving it.
Cops clearly didn't think the scene was funny, though .
