The last time the Duchess of Cambridge stepped out, she made a very sombre appearance at the Royal Albert Hall for Remembrance Day with Prince William, but she was all smiles during her outing on Tuesday. The Duchess of Cambridge spent her day with some supercute young students from Oakington Manor Primary School, who joined her at London's Natural History Museum. There, they had a children's tea party and painted dinosaur eggs to celebrate "Dippy" the diplodocus, a famous dinosaur skeleton in the museum's main hall. Although she didn't bring daughter Princess Charlotte along, Kate — who wore a stunning dress — was flanked by two adorable little girls at the table and chatted with them throughout the day. Of all the sweet moments Kate has had in 2016, this is definitely one of her most aww-worthy, don't you think?
