The headline of this article is so OTT, lol. I just watched the clip - he literally did a normal gesture that anyone would do, nothing sweet or secret about it! Don’t get me wrong, I like Wills and Kate - but the ridiculously sycophantic language in this article and others about them does make me laugh sometimes!
