Kate Middleton Is the Definition of Glamour and Perfection at the Queen's Diplomatic Reception

Prince William and Kate Middleton are clearly feeling the holiday spirit! After hosting a Christmas party for military families at Kensington Palace on Tuesday, the Duke and Duchess of Cambridge joined Prince Charles and Camilla, Duchess of Cornwall at Queen Elizabeth II's annual Diplomatic Reception. Kate, of course, made a dazzling appearance in a sparkly gown and the Lover's Knot tiara, while William suited up in a black tux for the white-tie event.

Will and Kate have been regulars at the reception since 2013. The fête is one of the queen's biggest parties and consists of the monarch meeting with representatives and staff from different countries. Missing from the fun, though, were Prince Harry and Meghan Markle, who were busy attending their first Christmas carol service together. Luckily, they'll all be reuniting for Christmas later this month.
