Princess Kate Middleton was all smiles while stepping out for a milestone day with first lady Melania Trump. Following a glamorous state banquet with President Donald Trump, Kate, 43, and Melania, 55, teamed up on Thursday, September 18, to meet members of the Scouts Squirrels program at Frogmore Gardens. The lucky Squirrels - the youngest group of the U.K.'s Scouts - were gearing up to earn their "Go Wild" badges by learning about nature. Kate and Melania both embraced earthy tones with their outfits in Windsor.
