Will Smith had to straighten out a Ukrainian reporter while walking the red carpet of the Men In Black 3 premiere in Moscow.
As the young journalist went in for the kill, we mean kiss, the 43-year-old actor quickly pushed him away, saying:
"What the hell is your problem, man!"
After the incident, Smith laughed it off and continued on with the rest of his interviews, responding:
"He's lucky I didn't sucker punch him!"
Big Willie will have a story to tell his wife when he returns home ... and so will the reporter! 'I just got back-handed by Will freakin' Smith!'
