Kate Middleton seemed to allude to Prince Louis with a quick quip during the French state visit. See what Princess Kate said about her son, Prince Louis.

For her state banquet gown, Kate chose a dark red Givenchy evening gown designed by Sarah Burton, who also designed the princess's wedding dress. Kate and William shared their looks ahead of the state banquet on social media, captioning a photo, "Ready for what promises to be a wonderful State Banquet this evening in Windsor."
