The loveliest best man speech.

As royal fans are aware, Kate Middleton and Prince William married in 2011 and they celebrated their seventh wedding anniversary in April of this year. However, we're still hearing about details of their big day including Kate's second dress and now, the details of Harry's best man speech. It turns out that Harry got quite emotional on the big day and rather than give a funny speech with jokes about his older brother, he said some lovely things about William and Kate's relationship. Jessica Jayne is the author of The Duchess of Cambridge: How Kate Middleton Became A Future Queen and in the book, she goes into detail about how Harry said that their relationship proved "inspiring" for him. According to Express, Harry kept referring to William as "the dude" (awww) in the speech and also said that he loved Kate like a sister. I mean, can you cope with the cuteness of it all. This isn't the first time we've heard of the fact that Prince Harry and his sister-in-law, Kate, Duchess of Cambridge get on well. He has a nickname for her after all, a sign they are pretty tight and as proved by his speech at their wedding, Harry looks up to his older brother and his wife. We love hearing about what happens behind the scenes with the royal family and are happy to hear they are just as close as they appear to be when you see them out and about on official engagements.
