Kevin Hart got HAMMERED at the Super Bowl -- and was so drunk , he dropped an F-Bomb live on the NFL Network.
Can't really blame Hart ... he's a hardcore Eagles fan and he had just watched his team beat the New England Patriots live in Minnesota.
But when they brought him on the "NFL GameDay Prime" post-game show with Deion Sanders and company ... he was hyped up, slurring and really, 3-sheets to the wind.
After Deion personally escorted him off the stage -- Hart left ... and made a drunken Instagram video trying to explain himself. It's pretty hilarious.
Enjoy the hangover.
