When i was in school, one of my friends went to stand outside the premier of Alexander (Edit : Not Mr. and Mrs. Smith) hoping to see Angelina Jolie.
She was signing autographs for fans and when she got to him he kinda stuck his face out and she properly kissed him full on. It was even in some of the national newspapers. We would have been 17/18 at the time, so it was a pretty big deal.
