On the Late Show tonight, guest Will Smith opens up about slapping a Ukrainian reporter who tried to sneak-kiss him on the red carpet.

"It's just awkward," he tells host David Letterman, who responds with, "I can see where it would be."

Smith goes on to say that officials at the Russian event apologized on behalf of the "journalist," and informed the actor that trying get celebrities to unwittingly make out with him was "his schtick," to which the MIB3 star replied: "Well, that's why his ass got schtuck."
