Don't try to get too fresh with the Fresh Prince!

Will Smith has a reputation for being one of the nicest guys in Hollywood, but a certain Ukrainian reporter got a rare taste of the "Ali" star stinging like a bee at the Moscow premiere of "Men in Black III."

The reporter in question, whom TMZ claims is known for this kind of "schtick," got a little too affectionate with the star on the red carpet, which prompted Smith to slap him and ask, "What the hell is your problem, buddy?" Smith tried to immediately laugh off the incident with the next reporters in line, but he was obviously a little rattled ("He's lucky I didn't sucker-punch him").

Oddly enough (or perhaps not oddly at all), this incident has us recalling the whole thing that went on with "Six Degrees of Separation" when Smith insisted that he wouldn't do any man-on-man kissing scenes. He obviously still feels the same way, almost 20 years later.

Beware the rage of Will below. "Men in Black III" opens here in the U.S. on May 25.
