He is going to kiss a girl in DB, that is a fact, so it is not like Katie is going to be his first on screen kiss, or real kiss since he stated already that he have had a girlfriend, I have watched all the interviews on the net and TV and every time he talks about Cho or Katie he does it with respect.
That is why I think this is rubbish as all the news we get from the Sun; they love to twist their interviews to make it sound more controversial.
