Parker was visiting the Bolshoi Theatre in Moscow when security guard Oleg Donstov offered to take the beauty inside for an up-close view of the venue, which was closed to the public due to renovations.
After the tour, Donstov ripped open his shirt and leaned in to kiss the actress, much to Parker's dismay.
Donstov immediately expressed his regret in not acting as a true ""professional"", and now his amorous actions have landed him in hot water with his wife, who saw the whole thing unravel on camera.
Parker is now trying to remedy the couple's marital issues by assuring the woman the kiss was harmless.
Recalling the ordeal during an appearance on The Late Show with David Letterman on Wednesday (07Sep11), Parker said, ""The guard was slightly abusive (physical) but I kind of understood that this was kind of the quid pro quo of the situation. So we came back out (of the Theatre)... and there were some paparazzi there. He became rather boastful and he ripped open his shirt... and he had a pen and he wanted me to sign his chest. And then he went in for a big kiss. And I just squealed like a lady and just ran.
""It was videotaped, and his wife saw it and their marriage is in trouble. It's the truth. His marriage is in trouble!
""And I had no means (of) communicating with this lady. I don't know her name, so I issued a statement that was like, you know, 'No harm, no foul. We understand each other. (It was) all in good fun.'""
