I didn't see anything there about a "legal" name change. "she would now be known to friends and family as "Kate." "
As far as "uncles," I have children who call me "aunt" even though I'm not a blood relative but a family friend. It's not an uncommon thing - just a sign of respect and affection. However, who knew you had to ask the person, or announce it to the press? It's just gross that he has to make such a big friggin' international announcement about everything that happens in his personal life. We don't really care who your kid calls "uncle."
