The new documentary on Queen Elizabeth II, Our Queen at 90 [1], aired in the UK on Sunday night and proved to be very enlightening indeed. Not only did it reveal Prince George's adorable nickname for his great-grandmother [2] and the surprising gift [3] Kate Middleton once gave the queen for Christmas, but also the fact that one of the royal family's favorite activities is teasing Kate for being . . . wait for it . . . too friendly.

"She has been very generous and not, sort of, been forceful at all in any of her views," Kate said about her grandmother-in-law. "I feel she's been there as a gentle guidance really for me. Everyone teases me in the family that I spend far too long chatting so I think I have still got to learn a little bit more and pick up a few more tips." If that doesn't confirm your love for the down-to-earth princess [4], nothing will. Check out which royal traditions Kate and Prince William are dedicated to keeping alive [5] for their children, and then see photos from their fun St. Patrick's Day outings [6] over the years!
